This error has recently appeared. I can no longer access the admin area and nothing is displayed on the website.
I have already deactivated all plugins and themes in an FTP manager, but the problem persists. So, the cause is not a plugin or theme, I guess.

Would be very grateful for help!

Il y a eu une erreur critique sur ce site.

It then asks for Hook Tag …. what goes here?
Do I need to create a custom function (I can use Code Snippets for this) which will send the form data?

It’s unclear to me how to use this feature (there is no example).

2. In front of admin there is a warning = > Achtung:?Dieses Plugin wurde?nicht?mit deiner aktuellen WordPress-Version getestet.

Maybe an update could solve all errors
