What i still found out:
I activate (only) bbPress again and can reach our homepage.
Then i clear all caches from WP Fastest Cache v1.1.1 and i get the error.
Via FTP i deactivate bbPress without clearing the cache and i can reach the homepage
I deactivated all bbpress related plugins too and got the same error. So in my opinion this error is not in the related plugins
And there are no error message in the developer console of the browser
That’s all what i saw, as i tried to reach our homepage
In this thread (see bottom) i found the code. I think is better to remove it…
Oh shit, yes, i added this in my child theme in funtions.php.
Sorry and many thanks for your help!
But strange is:
Only after I switched from http to https i had this problem.
Okay, is fixed and many thanks again. 🙂
Addition:
I only get this error (in Front- and Backend) when i logged in as Administrator in WordPress. If i logged in as Participant everthing is okay.
