WP-Optimize – Cache, Clean, Compress.


WP-Optimize Cache is a revolutionary, all-in-one WordPress performance plugin that caches your site, cleans your database, compresses your images.

Our cache feature is built around the world’s fastest caching engine. This simple, popular and highly effective tool has everything you need to keep your website fast and thoroughly optimized!

It does it in three clever ways:

  • It allows you to clean and optimise your database.
  • It gives you the option to compress your images.
  • It allows you to cache your pages, for super fast load times (read more caching information below).

It also enables you to minify and asynchronise CSS and JavaScript (aka. „defer CSS JavaScript“).

Extensive tests show the cache feature alone can make WordPress sites at least as fast as any other caching or speed plugin available and often faster. But when you combine the cache with the database optimization, image compression features and minify, the speed difference with alternative solutions is significant.

NEW: The built-in minify feature adds another layer of optimization, reducing the size and number of requests to your server.

1. Cleans the database

Your WordPress database stores everything that you need for your website – plus many things that you don’t. WP-Optimize Cache clears out all of this unnecessary data, cleans up your tables and even retrieves space lost to data fragmentation.

Mobile-friendly and incredibly simple to use, it:

  • Removes all unnecessary data (e.g. trashed/unapproved/spam comments, stale data) plus pingbacks, trackbacks and expired transient options
  • Compacts/de-fragment MySQL tables with a button-press
  • Detailed control of which optimizations you wish to carry out
  • Carries out automatic weekly (or otherwise) clean-ups
  • Retains a set number of weeks’ data during clean-ups
  • Performs optimizations without the need for running manual queries
  • Automatically trigger a pre-optimize backup via UpdraftPlus
  • Show database statistics and potential savings

Why is this important?

  • The tables in MySQL (the database that WordPress uses) will, over time, become inefficient as data is added, removed, moved around. Asking MySQL to optimize its tables every now and again will keep your site running as fast as possible. It won’t happen by itself.
  • Every-time you save a new post or pages, WordPress creates a revision of that post or page. If you edit a post 6 times you might have 5 copy of that post as revisions. This quickly adds lots of rarely-used data to your database tables, making them unnecessarily bloated, and slower to access.
  • There might be thousands of spam and un-approved comments in your comments table, WP-Optimize Cache can clean and remove those in a single click.
  • WP-Optimize Cache reports which database tables have overhead and wasted space to allow you to reduce them.
  • Automatically cleans your database every week and respects the “Keep last [selected number] weeks data” option.

WP-Optimize Cache helps you to:

  • Make space: When you edit a post or page on your website, WordPress automatically saves the new revision to the database. If you edit things a few times (and particularly if the post is long), your database soon gets clogged up with old revisions that just sit there, taking up valuable space. WP-Optimize Cache removes these unnecessary post revisions, freeing up valuable Megabytes of data and increasing speed and efficiency. It also cleans up your comments table, removing all the spam and un-approved comments that have built up with a single click.

  • Take control: WP-Optimize Cache reports on exactly which of your database tables have overhead and wasted space, giving you the insight, control and power to keep your website neat, fast and efficient.

  • Keep it clean and fast: Once enabled, WP-Optimize Cache can run an automatic clean-up on a schedule, keeping a selected number of weeks’ data, according to your specification.

2. Compresses images

Loading large images is often the biggest culprit in slowing your site’s loading time.

WP-Optimize Cache has an image-compression tool that uses cutting-edge lossy compression techniques to convert large images (which take a long time to load up) into compressed files saved in your image library, where they can be uploaded in an instant.

It enables you to compress PNG, JPG, GIF, BMP and TIF pictures up to 5MB in size, and it’s packed with other useful features, including:

  • Bulk compression, allowing you to compress multiple existing images at the same time.
  • Intelligent, multi-pass lossy compression algorithm, which gives you twice the compression with much less loss of quality.
  • ‘Restore Originals’ function, which allows you to retrieve or revert back to your original images at any point.
  • Auto-compress function, which automatically compress images as they’re added to the site.
  • EXIF Data-Keeping means image information is retained even once the image is compressed.

This WordPress plugin allows you to increase your page speed without compromising the image quality.

3. Caches pages

Depending on your setup, page caching can be what makes the biggest difference to your website’s speed and performance.

Caching involves keeping dynamic data in a temporary storage area so that it can be retrieved in an instant. Caching is a sure-fire way to ensure that web pages load at lightning-fast speed.

Practically, our powerful yet simple cache feature generates the cache when a user visits any page or post on your site. WordPress processes the dynamic php files to generate that page, and we save it into a static html file in the cache folder, so that when the next user visits, the page is cached and doesn’t need processing. This caching results in a much faster loading time, and gives a slight break to your server. So caching increases speed and performance while reducing the server’s use of resources.

With minimal configuration, caching your site with WP-Optimize Cache is easy to do thanks to a load of useful features, including:

  • Cache preloading to ensure the cache is always ready and loaded.
  • Gzip compression of HTML, JavaScript, and CSS to reduce site load time.
  • Device-Specific cache to ensure the optimized page version is always served.
  • Advanced cache exclusion rules, so that you can cache almost anything by excluding logged in users, specific URLs or cookies.
  • Browser Cache to instruct client browsers to reuse cached resources (HTML, CSS, JS, images) if no changes were made since the last request.

Minify and combine CSS and JavaScript

On top of its three main features, WP-Optimize Cache also has the more advanced minification feature. Combining and minifying your site’s assets will reduce the number of requests to your server (by combining them) and reduce their size (by minifying their content).

Together with caching and Gzip compression, this will improve the performance and time to „first contentful paint“.

The minify feature also enables you to defer CSS and JavaScript. Defering CSS and JavaScript allows you to load non-critical assets after the main page load, resulting in an apparent speed gain. Minifying and defering CSS and JavaScript also makes Google PageSpeed Insights happy!

Overall WP-Optimize brings the best cache and optimization technology together in a single seamless plugin to make your WordPress site fast, lean and efficient.

WP-Optimize Cache Premium

Our free version of WP-Optimize Cache is great, but we also have an even more powerful Premium version with extra features that offer the ultimate in freedom and flexibility:

  • Multisite Support: extends database optimisations so they function for multiple WordPress sites at a time. If you manage more than one website, you will need WP-Optimize Cache Premium.
  • Flexibility and Control: gives you the power to optimize select individual tables or a particular combination of tables on one or more WordPress websites, rather than having to optimize all database tables.
  • Deleting unused and unwanted images: removes orphaned images from your WordPress site, plus images of a certain, pre-defined size.
  • Sophisticated Scheduling: offers a wide range of options for scheduling automatic optimization. Specify an exact time and run clean-ups daily, weekly, fortnightly or monthly and perform any number of additional once off optimizations.
  • Seamless Graphical User Interface: for superb clarity in scheduling and managing of multi-site optimizations.
  • WP-CLI support: provides a way to manage optimizations from command-line interface if you have lots of sites
  • Lazy Loading: load only the images and part of a web-page when it is visible to the user so they can see something very quickly.
  • Optimization Preview: gives users the ability to preview, select and remove data and records available for optimization from the database.
  • Preload key requests: preload assets such as web fonts and icon fonts, as recommended by Google PageSpeed Insights.
  • Premium support – caching is one of the most complex things you can do for a website, so premium support offers you peace of mind there’s someone to talk quickly to if you need any technical answers or help configuring the optimizations of cache settings for your website.

Časté otázky

Isn’t it better to use a dedicated caching plugin to cache my site?

We’ve built WP-Optimize Cache around the most advanced and powerful caching technology. Our caching tests and feedback from real-world users show that the caching feature alone can make your site faster than any other cache plugin or optimization. See these speed test results.

Is optimizing my database safe?

Yes; optimizing does not involve any „tricks“ or poking around in dangerous ways. It involves running routine clean-up operations using well-defined, common MySQL commands. Nevertheless, we always recommend backups, which cover every possibility; not just database malfunctions, but hackers, human errors, etc. We recommend UpdraftPlus.

What savings can I expect to make?

This is a „how long is string?“ sort of question. It depends completely on your site – how big it is, how many users interact on it, how long it has been running, and when you last optimised it. However, the savings and speed-ups can be substantial; it is always worth making sure that your database is optimised.

How do I get support?

In our support forum, here: https://wordpress.org/support/plugin/wp-optimize/

How do I use WP-Optimize Database Cleaning?

WP-Optimize does not make large savings on my database

This is rare; it’s probably because you’re with a shared web hosting company that doesn’t allow scripts to run an optimize command via SQL statements (SQL „OPTIMIZE“ instruction). Please consult your web hosting company on this matter.

Is the plugin tried and tested?

Yes – WP-Optimize Cache is WordPress’s #1 most-installed optimisation plugin, with over 800,000 users and a pedigree going back over 8 years.

Does WP-Optimize support InnoDB tables?

WP-Optimize will disable some features if it detects InnoDB tables. Optimization of the database tables on-disk is not available, but other clean up features would work.

Can you help me restore my database?

Not unless you have an existing backup. Please ensure that you make a backup of your entire database before using WP-Optimize for the first time, and when you upgrade to a major new version of it. We recommend UpdraftPlus.

Are there any bugs in this plugin?

The plugin is an ongoing work; that means that it is impossible to rule out unforeseen situations and bugs. So I would recommend you to test it out on your local system or make a backup of your database (just to be extra careful).

How do I stop transient options from coming back automatically each time I clear them?

When WordPress uses a particular transient, that specific transient is re-created automatically. So, it’s normally for ones which are in active use to gradually re-appear. The best way to keep things optimal is to clear the transient options on a scheduled basis. For example, WordPress may create 50 transient option in a week. If you schedule WP-Optimize Cache to clear these options on a weekly basis, you’ll have far fewer building up.

The table size shows wrong / Not optimizing

Please check your database for corrupted tables. That can happen, usually your web hosting company can run the repair command on the db.

Which WordPress and PHP versions are supported?

To use all features in the plugin, a minimum of version WordPress 4 with PHP 5.3 are required. But we do recommend to use the latest version of WordPress. Using PHP 7+ is also highly recommended, as our caching feature will work even faster.

Which optimisation will make the biggest difference?

This depends on your setup (theme, number and quality of plugins used, etc…), but generally, caching will make the biggest visible difference to your website’s performance. Indeed, the cache functionality bypasses most of WordPress code to serve your pre-optimised cached pages directly to your visitor, significantly increasing the speed.

What is caching, or page caching?

„Caching“, from Wikipedia: „In computing, a cache is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot.“ — WP-Optimize cache does this by saving the page computed by WordPress on the disk. When a user visits a page, WP-Optimize will serve the cached page before WordPress is loaded. If the page wasn’t cached before, it will be computed by WordPress, and WP-Optimize will then save the result to the cache.

Why should I use a caching plugin on my website?

You think your site is fast without caching? A caching plugin will make your website even faster. A faster cached website will increase SEO, it will improve your visitors experience. Caching will also save your server’s resources.

Is the WP-Optimize page cache compatible with Gutenberg and WordPress 5.0+?

Yes, your Gutenberg pages will be cached, as well as those created with page builder plugins such as Elementor.

How do I know my webpage is being cached (or why it isn’t)?

If cache is enabled, and in order to see if your page is cached, use the “View Source” function in your web browser to view the page source. To find caching information, scroll down to the bottom, and you should see a line added by the cache: <!-- Cached by WP Optimize - https://getwpo.com - Last modified: Sat, 20 Jul 2019 21:17:19 GMT ->
However, note that if you are using a further service that minifies HTML (e.g. Cloudflare), then this line may have been removed. Another method is to inspect the contents of the directory wpo-cache inside your wp-content directory. <a href=“https://getwpo.com/faqs/how-do-i-know-my-webpage-is-being-cached/>Further information can be read here
Also note that if you do not preload the cache, a page or post will have to be visited once for the cache file to be generated.

How do I configure the page cache?

Prejdite do WP-Optimize -> Vyrovnávacia pamäť a zapnutie vyrovnávacej pamäte. Pre väčšinu ľudí to bude stačiť. Ak prevádzkujete elektronický obchod, máte vlastnú prihlasovaciu stránku alebo akúkoľvek stránku s dynamickým obsahom, možno budete chcieť vylúčiť určité adresy URL z vyrovnávacej pamäte. Viac informácií o vylúčení adresy URL z vyrovnávacej pamäte nájdete v časti Rozšírené možnosti ukladania do vyrovnávacej pamäte v našej dokumentácii k vyrovnávacej pamäti.

Is the caching feature compatible with e-commerce plugins?

Áno, ukladanie do vyrovnávacej pamäte pomocou nástroja WP-Optimize vám umožňuje bezpečne ukladať vaše produkty prostredníctvom doplnkov ako WooCommerce alebo Easy Digital Downloads alebo akéhokoľvek elektronického obchodu, ktorý používa DONOTCACHEPAGE na vylúčenie citlivých stránok z vyrovnávacej pamäte (napr. Môj účet, košík alebo pokladničné stránky).

Is the caching feature compatible with multilingual plugins?

Yes, WP-Optimize works with popular multilingual plugins like WPML or Polylang. However, it’s important to note that when using WP-Optimize with multilingual plugins, the URL format for different languages should not include any query parameters, for example https://example.com/?lang=en. Instead, it should be in a pretty permalink format, such as https://example.com/en.

Do I need a special setup to use the caching feature?

Nie, ak WordPress funguje správne, WP-Optimize bude môcť ukladať vaše stránky a príspevky do vyrovnávacej pamäte.

Can I use the page caching feature together with another cache plugin?

Nie, pretože obidva doplnky do vyrovnávacej pamäte by museli používať doplnkový modul advanced-cache.php . Ak vypnete ukladanie do vyrovnávacej pamäte na WP-Optimize, môžete použiť akýkoľvek iný doplnok pre ukladanie do vyrovnávacej pamäte a stále používať ďalšie funkcie WP-Optimize. Odporúčame však použiť naše riešenie na ukladanie do vyrovnávacej pamäte.

Is WP-Optimize caching compatible with Cloudflare?

Áno! Nie je potrebná žiadna špeciálna konfigurácia vyrovnávacej pamäte. Ukladanie stránok do vyrovnávacej pamäte na webe WP (ktoré vykonáva technológia WP-Optimize) je nezávislé od vyrovnávacej pamäte proxy (napr. Cloudflare) – môžete použiť oboje alebo žiadne, a budú sa navzájom dopĺňať a nezasahujú.
Jediná vec, ktorú si treba zapamätať – Cloudflare odstráni špeciálny komentár HTML v dolnej časti zdroja stránky, ktorý je užitočný na potvrdenie toho, že ukladanie stránok do pamäte funguje, takže sa tým nemýľte – je to absencia neznamená, že cache nefunguje.

Can I empty the cache automatically when performing a custom action?

Áno, môžete spustiť akciu vymazania vyrovnávacej pamäte pomocou verejných funkcií WP-Optimize. Ak chcete vymazať celú vyrovnávaciu pamäť, použite funkciu wpo_cache_flush () . Ak chcete vymazať súbory vyrovnávacej pamäte pre konkrétnu stránku alebo príspevok, použite WPO_Page_Cache :: delete_single_post_cache ($ post_id); . Tieto možnosti vyrovnávacej pamäte sú dostupné po akcii WP plugins_loaded .

Will the comments work even when page caching is enabled?

Áno, pri používaní systému komentárov WordPress budú vaši používatelia môcť uverejňovať komentáre. Vždy, keď je komentár schválený, vyrovnávacia pamäť pre danú stránku alebo príspevok sa vymaže, čo umožní ďalšiemu návštevníkovi zobraziť aktuálny zoznam komentárov.

What is „cache preloading“?

Stránka sa zvyčajne ukladá do vyrovnávacej pamäte, keď ju používateľ navštívi. Prvému používateľovi, ktorý navštívi, sa preto nezobrazí verzia stránky v pamäti a bude čakať dlhšie ako ďalší používatelia. Funkcia predbežného načítania do vyrovnávacej pamäte prechádza všetkými vašimi stránkami a príspevkami a simuluje návštevu používateľa, čo umožňuje optimalizácii WP-Optimalizovať stránky do vyrovnávacej pamäte skôr, ako ich niekto navštívi. Vášmu prvému návštevníkovi sa preto zobrazí verzia stránky v pamäti, ktorá zvyšuje jej výkonnosť.

What frequency should I choose for the cache preloading schedule?

Výber frekvencie pre plán predbežného načítania vyrovnávacej pamäte bude závisieť od faktorov, ako je napríklad frekvencia aktualizovania obsahu webovej stránky, počet stránok v vyrovnávacej pamäti, zdroje servera a ďalšie.
Napríklad web so stovkami stránok bude vyžadovať viac zdrojov na predbežné načítanie jeho vyrovnávacej pamäte. Takže voľba vysokej frekvencie bude znamenať, že vyrovnávacia pamäť bude často vytvorená a využitie zdrojov bude vyššie.
Na webových stránkach, kde aktualizácie nie sú také časté, môžete dokonca vypnúť plán predbežného načítania vyrovnávacej pamäte alebo nastaviť vysokú životnosť vyrovnávacej pamäte a nastaviť časový plán predbežného načítania vyrovnávacej pamäte, aby sa riadil.

How do I cache only the home page?

Pridať /.+ do cache voľbu „URL vylúčiť z medzipamäte“ na karte Rozšírené nastavenie.

How do I prevent WP-Optimize Cache from caching a certain page

Ak chcete zabrániť ukladaniu stránky do vyrovnávacej pamäte, môžete adresu URL pridať do poľa „URL na vylúčenie z vyrovnávacej pamäte“ na karte „Rozšírené nastavenia“ v vyrovnávacej pamäti. Ak vyvíjate doplnok a chcete zabrániť ukladaniu stránky do vyrovnávacej pamäte, môžete na stránkach, ktoré potrebujete, definovať konštantu „DONOTCACHEPAGE“. Žiadosť, v ktorej je definovaná položka „DONOTCACHEPAGE“, nebude uložená do vyrovnávacej pamäte.

Is the caching feature of WP-Optimize free?

Áno, funkcia ukladania do vyrovnávacej pamäte je zadarmo. Vždy budete môcť bezplatne ukladať svoje webové stránky do vyrovnávacej pamäte pomocou WP-Optimize a neustále pracujeme na vylepšovaní existujúcej funkcie vyrovnávacej pamäte. K bezplatnej verzii pridáme ďalšie možnosti ukladania do pamäte cache a v prémiovej verzii budeme vyvíjať konkrétnejšie možnosti ukladania do pamäte cache, aby ste mohli prispôsobiť funkcie ukladania do pamäte cache vašim potrebám.

Where does WP-Optimize Cache store the cached files?

Súbory v vyrovnávacej pamäti sa ukladajú do spoločného priečinka „wp-content / cache“, vnútri priečinka „wpo-cache“. Odstránením priečinka „cache“ sa odstránia všetky medzipamäte programu WP-Optimize, ako aj súbory z iných doplnkov.
Vymazanie priečinka „vyrovnávacia pamäť“ je vo všeobecnosti bezpečné, pretože súbory v vyrovnávacej pamäti sa obnovia.

How do I disable caching?

Prejdite na nastavenia optimalizácie WP; Zapnite / vypnite vyrovnávaciu pamäť a prepnite možnosť „Povoliť ukladanie stránok do vyrovnávacej pamäte“.

Will caching slow down my server?

Nie, ukladanie do vyrovnávacej pamäte skutočne zníži zaťaženie vášho servera znížením množstva použitých PHP a mysql. Pri použití nástroja na načítavanie vyrovnávacej pamäte by ste mohli vidieť vrchol v používaní zdrojov, pretože táto funkcia vytvorí súbory vyrovnávacej pamäte pre všetky vaše stránky v krátkom čase. Po dokončení by sa však výkon mal zvýšiť a záťaž servera sa zníži. Každý hlavný web používa ukladanie do vyrovnávacej pamäte na rýchlejšie zobrazovanie stránok v vyrovnávacej pamäti pomocou menšieho množstva zdrojov.

Can I make certain parts of the page stay dynamic when cache is enabled?

Stránka v vyrovnávacej pamäti sa používateľovi odošle skôr, ako sa načíta väčšina WordPress. Doplnky ešte nie sú načítané, čo im znemožňuje meniť obsah v vyrovnávacej pamäti pri každej žiadosti.
Takže ak chcete, aby časti vašej stránky zostali dynamické (napr. Reklamy, widgety, nákupný košík …) A aby boli uchované v vyrovnávacej pamäti, na načítanie týchto dynamických častí zo servera budete musieť použiť vlastné riešenia pomocou javascriptu a AJAX. ,

How do I delete the WP_CACHE define from wp-config.php?

Aplikácia WP-Optimize odstráni konštantu „WP_CACHE“ z wp-config.php, keď zakážete ukladanie stránok do vyrovnávacej pamäte alebo keď deaktivujete doplnok cache. Ak ho potrebujete odstrániť manuálne, môžete použiť FTP na úpravu wp-config.php a vymazať definíciu riadku (‚WP_CACHE‘, true);
Ak je v nastaveniach stále zapnuté ukladanie do vyrovnávacej pamäte, program WP-Optimize sa pokúsi znova pridať riadok, pretože je potrebné, aby fungovala funkcia ukladania do vyrovnávacej pamäte.

My filesystem is not writable to increase security. What do I need to do to make it compatible with the caching functionality?

Funkcia ukladania do vyrovnávacej pamäte WP-Optimize vyžaduje prístup na zápis do priečinka „wp-content / cache“, pretože tu sa budú ukladať súbory vyrovnávacej pamäte. Tiež musí definovať konštantu ‚WP_CACHE‘ v ‚wp-config.php‘, bude potrebovať prístup raz do ‚wp-content / advanced-cache.php‘, ako aj do priečinka ‚wp-content / wpo- cache ‚na zapísanie nastavení vyrovnávacej pamäte.

How do I change file permissions?

Ak potrebujete zmeniť povolenia súborov na zapnutie ukladania do pamäte cache, môžete postupovať podľa pokynov na tejto stránke https://wordpress.org/support/article/changing-file-permissions/

What is the maximum number of pages I can cache?

Počet stránok, ktoré môžete ukladať do vyrovnávacej pamäte, nie je nijako obmedzený. Jediným obmedzením je priestor na vašom serveri a maximálny počet podadresárov, ktoré váš server povolil, pretože ukladanie do vyrovnávacej pamäte zapisuje súbory do podadresárov podľa štruktúry permalink.
Ak by ste dosiahli limit vyrovnávacej pamäte, pravdepodobne to znamená, že váš server nie je vhodný pre veľkosť vášho webu a potreby ukladania do vyrovnávacej pamäte.

How do I serve cached pages to people using a phone or tablet?

Samostatnú vyrovnávaciu pamäť môžete vygenerovať výberom možnosti „Vygenerovať samostatné súbory pre mobilné zariadenia“ v nastaveniach vyrovnávacej pamäte stránky. Toto nastavenie vyrovnávacej pamäte je potrebné iba v prípade, ak používate špecifickú tému pre mobilné zariadenia alebo pre určité doplnky AMP.

Does WP-Optimize Cache work with Nginx?

Áno, funkcia vyrovnávacej pamäte spolupracuje s Nginx. Ak chcete povoliť ukladanie do vyrovnávacej pamäte prehliadača alebo kompresiu GZIP, musíte to urobiť priamo v nastaveniach servera.

Does caching work with Windows Server (IIS) ?

Áno, funkcia vyrovnávacej pamäte funguje so službou IIS. Rovnako ako v prípade Nginx, ak potrebujete povoliť ukladanie do vyrovnávacej pamäte prehliadača alebo kompresiu GZIP, budete to musieť urobiť sami na serveri.

Does the WP-Optimize page cache work with non-pretty (query parameter-based) permalinks?

Nie. Aby fungovala vyrovnávacia pamäť, je potrebné mať dosť permalinky typu http://xxxxx.com/my-post/ a nie http://xxxxx.com/?p=1234. Predvolené nastavenie WordPress je dosť permalinkov a neexistuje žiadny dobrý dôvod na ich vypnutie, preto by ste s tým nemali mať problém.
Pamätajte, že vyrovnávacia pamäť bude pracovať s permalinkmi vrátane /index.php/. Iba tie, ktoré sú založené na parametroch dotazu (? …), kde nebude fungovať vyrovnávacia pamäť.

When does WP-Optimize clear the page cache?

  • When you publish new content or update/edit existing content, the cache for that post/page will be cleared.
  • Changing/updating current themes and parent themes (of child themes) will purge the cache.
  • When turning off the cache feature in WP-Optimize

Will pages in the WP admin dashboard be cached?

Nie, stránky dashboardu WP nie sú uložené v pamäti cache. Funkcia vyrovnávacej pamäte slúži iba na ukladanie do vyrovnávacej pamäte frontendové stránky.

What is cache lifespan?

The cache lifespan is the time a cached file will be kept before being regenerated.
One of the main reason for setting a lifespan to your cache is that some plugins and themes use nonces, which are printed in the source code of the page (Read more about nonces here). These nonces cannot be reused and are valid for 12 hours by default (developers can change that value). The cache plugin will store the nonce in the page, and this one will become invalid after that perdiod of time, which can affect certain functionalities of your plugins and themes. Setting a cache lifespan to under 10 hours ensures the cache is flushed automatically before the nonce expires. This way you can use WP-Optimize’s cache feature on sites which use nonces.
An other reason is that you may want your pages to reflect some changes without having to clear the whole cache. Indeed if you have many pages and posts, you might not want to clear every cache file with every change, but rather set an interval at which they will expire and be regenerated.

What value should the cache lifespan be?

Nižšia hodnota životnosti vyrovnávacej pamäte bude mať za následok častejšiu aktualizáciu vyrovnávacej pamäte na vašom serveri, a ak bude aktivovaná, bude viac procesov predbežného načítania.
Ak vaše stránky nepoužívajú nonces a vyrovnávacia pamäť vašej stránky sa nemusí často aktualizovať, môžete nastaviť životnosť vyrovnávacej pamäte na vysokú hodnotu alebo na 0, aby ste jej dali nekonečnú životnosť.
Voľba životnosti vyrovnávacej pamäte je predvolene nastavená na 10 hodín, ale môžete ju znížiť na 8 alebo menej.
Ak si všimnete nejaké problémy kvôli vysokému zaťaženiu servera, nastavte pre predbežné načítanie vyšší interval.

Can WP-Optimize Cache minify JavaScript, CSS and HTML?

Yes, the newly added Minify enables you to minify JavaScript and CSS. It also enables you to minify HTML.

What is „Minify“?

Why minify my WordPress site?

WP-Optimize Cache’s Minify feature is all about increasing the speed of your WordPress site for your users.
One way Minify does this is by reducing the size of your HTML, CSS and JavaScript files by removing unnecessary spaces and lines from the files and shortening long names internally within the code.
Another way is that your files are merged into as few files as possible. This reduces the amount of load on your web server and can be quicker to load fewer files.
You can also defer the loading of any CSS or JavaScript file. This means any large or extraneous CSS or JavaScript file can be loaded independently from the core of your WordPress site; giving your users quicker access to your site.

What does “Reset the minified files” actually do?

Pressing the “Reset the minified files” does:
* delete the temporary files used when generating the minified assets
* delete old minified files (more than 30 days old)
* add a folder for the new minified files, which will be generated when visiting a page
The previously minified CSS files will remain on the server until they expire, or until they’re deleted using the button “Delete all the files generated by minify”.

Can I defer CSS and JavaScript using WP-Optimize Cache?

Yes, the newly added minification feature (a.k.a. Minify) allows you to defer parsing of JavaScript and CSS.

Google’s PageSpeed Insights says to leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Can WP-Optimize Cache do that?

Leveraging the font-display CSS feature is currently possible when using Google Fonts. The default parameter is „swap“, but can be changed using the WordPress filter „wpo_minify_gfont_display_type“.

When enabling minify, my site’s layout is broken. How can I fix it?

This usually means one or more of your CSS files are incompatible with the minification or merging process. It can also be caused by errors in the CSS’s syntax.
You can check the CSS’s syntax by using an online CSS syntax checker such as csslint.net.
If your syntax is not causing the issue, or you cannot change the file with an issue, you can either exclude the problematic CSS files from the minification and merging process.
To exclude individual CSS files from the minification and merging process, you can go to WP-Optimize > Minify > CSS and go to the “Exclude the following CSS files from processing” section.

When enabling minify, some functionality is broken. How can I fix it?

This usually means one or more of your JavaScript files are incompatible with the minification or merging process. It can also be caused by errors in the JavaScript’s syntax.
The first thing to try is to enable the setting “Contain each included file in its own block” in the JavaScript options (WP-Optimize > Minify > Javascript > JavaScript options). This could “catch” an error, and prevent the rest of the code to be broken.
If the first option didn’t work, try disabling merging of JavaScript files.
If none of the above works, disable processing of JavaScript files in the minify settings, and open a support thread with details about your issue. We’ll do our best to help you troubleshoot the issue.

How do I use the image optimisation feature?
