MORE THAN A CACHING PLUGIN

WP-Optimize is trusted by more than 1 million WordPress website owners to boost performance and reduce page load times to improve your site’s user experiences and SERP rankings in Google.

It does this in four clever ways:

1. It caches your site

Caching is the process of storing a temporary HTML version of your site on the server so it can be retrieved more quickly for the user.

It’s a sure-fire way to ensure web pages load at lightning-fast speed. Turn it on in just one click.

2. It compresses images

Large images can really impact page speed load times. WP-Optimize makes it easy to identify and compress images to your preferred lossy / lossless settings in a couple of clicks.

3. It cleans the database

Your WordPress database stores everything that you need, plus some things that you don’t. WP-Optimize cleans and optimizes the database to speed up your site and save server resources.

4. It minifies

On top of its three main features, WP-Optimize Cache also has the more advanced minification feature.

Together with caching, minification dramatically improves performance and page speed load time.

1. CACHE YOUR SITE

Turn on caching in just one click:

WP-Optimize automatically and optimally configures itself for your WordPress site. Turn it on in one-click or refine its settings if you prefer.

More cache features:

Cache preloading: This feature emulates a visit to your site, meaning cached files are served straight away, speeding up your site from the very first visit.
GZIP Compression: When the server isn’t configured to do so, WP-Optimize delivers HTML, CSS and JS files to the user’s browser as smaller, compressed files, reducing the size of pages and style sheets by up to 90%!
Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster [Premium].

Use cache settings to:

Serve cached content to logged in users: Turn this on if content stays the same for logged in users (or turn on and exclude URLs where content does change e.g. my account areas).
Exclude content from cache: Exclude by URL, conditional tags, browser agent strings or list cookies that should prevent caching when set (advanced user settings).
Deliver device-specific cache: Serve separate cache files to desktop and mobile devices . This ensures that responsive features e.g. desktop and mobile menus are cached separately and served correctly.
User per role cache: Useful if your website delivers different content to different user roles. e.g. an e-commerce site that displays different content to resellers or consumers [Premium].
User specific cache: Serves separate cache files to individual users. Useful for websites with personalised content e.g. Learning management systems [Premium].
Cache purging permissions: Select which user roles are allowed to purge the cache e.g. admin only or perhaps a ‚teacher‘ role in an LMS setting only [Premium].

2. COMPRESS IMAGES

Lossy or lossless compression options: Choose between maximum space saving, best image quality or somewhere in-between.
WebP conversion: Recommended by Google, WebP can achieve up to 34% smaller file sizes compared to JPEG and up to 26% compared to PNG.
Auto-compress: Check a box and every new image you upload will automatically be compressed to your preferred lossy / lossless settings.
Bulk compression: Compress every existing image on your site with the press of a button.
Restore original: Gone too far? Revert images back to their original in one click.
Retain EXIF image data: Check a box to retain EXIF image data during compression.
Lazy Load: Webpages load much faster by loading web parts gradually, when they’re needed vs simultaneous loading of everything, all at once [Premium].
Delete orphaned images: Identify and delete unused images from your WordPress website, saving disk space [Premium].
Delete unused image sizes: WordPress creates multiple sizes for every uploaded image causing the uploads folder to become bloated. Scan for image sizes not in use and remove them to save further disk space [Premium].

3. CLEAN AND OPTIMIZE THE DATABASE

Cleans-up database tables, post revisions, auto draft posts, trashed posts, spam, trashed comments and more. Choose what to optimize or it’s one click to clean out the lot.

Schedule clean-ups: So you can set and forget. Choose from daily, weekly, fortnightly or monthly.
Flexible clean-up schedules: You may wish to optimize database tables more frequently than you remove unapproved comments (for example). Choose the specific time and day when tasks should run [Premium].
Retain a set number of weeks‘ data during clean-ups: Just in case you need to retrieve something.
Back up before clean-ups: If you delete something you shouldn’t, restore it in a couple of clicks with UpdraftPlus.
Power tweak – Turbo boost for WooCommerce: Unique to WP-Optimize, this power tweak boosts performance by replacing a slow query in WooCommerce with two much more efficient queries. E-commerce sites transacting high numbers of orders stand to gain here [Premium].
Power tweak – Boost performance by indexing the postmeta table: This unique power tweak works by allowing the WordPress postmeta table to be indexed, improving performance [Premium].

4. MINIFY AND COMBINE HTML, CSS AND JAVASCRIPT

Minify in just one click: Minifies HTML, JavaScript and CSS. Toggle on or off or customise each one under ‚settings‘.
Customise minification: Minify only (removing unnecessary code e.g line breaks and white spacing) or minify and merge. Apply the same or different settings to HTML, CSS and JavaScript.
Asynchronous loading: Choose non-critical CSS and JavaScript files to load in the background and independently of other resources e.g. analytics or pixel scripts. Loading asynchronously eliminates render blocking and improves page speed.
Exclude files from being minified: Specify CSS and JavaScript files to exclude from minification.
Optimize fonts: Optimize Font Awesome and Google Fonts. Inline the font files, inherit from CSS settings or load CSS / Javascript asynchronously instead.
Preload assets: WP-Optimize visits each web page on your site so the code is minified and preloaded for real life users, right from their very first visit.
Preload key requests: Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster.

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 WP-Optimize Cache) je nezávislé od ukladania do vyrovnávacej pamäte proxy servera (napr. Cloudflare) – môžete používať obidve alebo ani jednu z nich a budú sa navzájom dopĺňať a nebudú si prekážať.
Jednu vec treba poznamenať – Cloudflare odstráni špeciálny komentár HTML v spodnej časti zdroja stránky, ktorý je užitočný na potvrdenie toho, že ukladanie do vyrovnávacej pamäte stránky funguje, takže sa tým nenechajte zmiasť – jeho neprítomnosť neznamená, že vyrovnávacia pamäť 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?

Pridajte /.+ do možnosti vyrovnávacej pamäte „URL adresy, ktoré sa majú vylúčiť z vyrovnávacej pamäte“ na karte rozšírených nastavení.

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

Ak chcete zabrániť ukladaniu stránky do vyrovnávacej pamäte, môžete pridať adresu URL do poľa „URL, ktoré sa majú vylúčiť z vyrovnávacej pamäte“ na karte „Rozšírené nastavenia“ vyrovnávacej pamäte. Ak vyvíjate doplnok a chcete zabrániť tomu, aby sa stránka ukladala do vyrovnávacej pamäte, môžete na potrebných stránkach definovať konštantu „DONOTCACHEPAGE“. Všetky požiadavky, pri ktorých je definovaná konštanta „DONOTCACHEPAGE“, sa nebudú ukladať 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 medzipamäti sú uložené v spoločnom priečinku „wp-content/cache“ v priečinku „wpo-cache“. Odstránením priečinka „cache“ sa odstráni všetka vyrovnávacia pamäť WP-Optimize, ako aj vyrovnávacia pamäť iných zásuvných modulov.
Odstránenie priečinka „cache“ je vo všeobecnosti bezpečné, pretože tieto súbory vyrovnávacej pamäte sa obnovia.

How do I disable caching?

Prejdite na WP-Optimize settings > Cache a prepnite možnosť „Enable page caching“ na on/off.

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 WP-Optimize caching potrebuje prístup na zápis do priečinka „wp-content/cache“, pretože tu budú uložené súbory cache. Potrebuje tiež definovať konštantu ‚WP_CACHE‘ v súbore ‚wp-config.php‘, raz bude potrebovať prístup do súboru ‚wp-content/advanced-cache.php‘, ako aj do priečinka ‚wp-content/wpo-cache‘, aby mohla zapísať nastavenia 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 vytvoriť výberom možnosti „Generovať samostatné súbory pre mobilné zariadenia“ v nastaveniach vyrovnávacej pamäte stránky. Toto nastavenie vyrovnávacej pamäte je potrebné len v prípade, že 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?

Sehr gutes Datenbank-, Speicher- und Optimierungstool. Danke

Magic, it optimizes everything perfectly, but you have to be careful and do a balanced optimization, so as not to break your website, and taking into account the limitations of your hosting server. I don't give it 10 stars because you can't.
