Hi @memet569
As for Facebook:
Facebook makes modifications in the Apps very often, and sometimes you need to make adjustments in your App otherwise Facebook might deactivate your App.
The good news is that, when they make such changes, they usually send you an email where they inform you any action that you might need to do. For example:
- earlier they introduced the “User Data Deletion” field.
- then they started introducing a new permission system with Standard Acces and Advanced access
- and recently they started disabling the login with Apps, if the App doesn’t have Privacy Policy URL, User Data Deletion, App Icon, Category, App Purpose set or if the URL that you entered into the Privacy Policy URL, User Data Deletion fields earlier are invalid or not accessible.
Anyways if you check your Facebook App, then Facebook usually display warnings for these, so you will know if something is wrong.
But as always, if you receive an email from “Facebook for Developers”, then you should always read it, as it may warn you about upcoming changes and if you miss those Facebook might deactivate your App, until you make the necessary adjustments.
As for the problem that I see on your site:
I tried to check the problem on the linked page and currently I can only see a critical error that happens as soon as I open your homepage. Since it is only a general WordPress error message, I can not really tell what is the problem exactly, but as I see you also opened a support ticket about this problem, and there I gave you some tips for enabling the error reporting on your site, so we could find out what is the problem exactly.
Could you check my message there, please?
Best regards,
Laszlo.
