display problem

Hi.

Please can you help me with the website http://www.staryhostinec.sk.

Some articles on the page stopped appearing a few days ago. For example, after entering the address of the article https://www.staryhostinec.sk/citadela-01-archa-architektury/ will be displayed, and the article https://www.staryhostinec.sk/ubytujte-sa-v-starom-hostinci-svaty-anton-banska-stiavnica/ is not loading. Can you check where the error might have happened? When I disable the preloader, on page is the error message. Thanks for help.
