If this is already at the beginning of the file, is this still recommended?
Would we add this anyway leaving them both in place, remove the one from the beginning of the file in addition to adding this to the end, or leave it as-is without adding it at all?
Hello @Greg P,
One is sufficient, no need to add the record twice.
It is showing for all the websites on the server. How to fix over 200 websites ??
Hello @Salman,
Am I correct that you have the same issue for all of these websites?
Have you tried the above steps for some of the websites?
For this particular issue, the solution doesn't look scalable.
In case the issue is different, please, create a request to Plesk Support to have a closer look at the issue.
Hello. Unfortunately I have this issue for two domains. One was solved by this tip:
in the wp-admin/load-styles.php file, change "error_reporting(0);" to "error_reporting( E_ALL | E_STRICT );" then refresh the page, if the page style return to normal, reverse the code change to it's initial state, and your site should look fine.
The second one I can not fix with any solution
Regards
Hello,
Actually, this is not a solution; this WordPress functionality should work.
What is the problem in nginx for this error?
I have tested on other servers with nginx (not plesk) this WordPress functionality works fine.
What is failing in plesk?
The concatenation of scripts, helps the loading speed of the wordpress backend.
How can it be corrected?
Greetings, Thank you.
