Hello.
Here is an example on Incomedia WebSite X5 Pro 2024.1.3 (hosted by Incomedia).
As far as I can see, everything is fine.
Please provide a link to your site.
What version of PHP are you using?
1) Delete all site files from the hosting.
2) Re-upload the entire site to the hosting (entirely, not just the changes).
3) Clear your browser cache and check. You can find out how you can clear your browser cache here.

Hello Serhii,
in addition to Aleksej's suggestions, I would recommend contacting the hosting provider's support to check if they have details about the errors, either in an error log or other systems, as Generic errors usually do not provide information when inspecting the page from the outside.

I have exactly the same problem and use PHP 8.3 (latest). Providers says the problem lies within the programm.
