WordPress Backend broken (load-scripts.php error 400)
-
Hi,
this happened on two different Sites now. When accessing the backend everything looks like pure html without any styling or layout. I also get an Error 400 in the console for the load-scripts.php file.
I wonder if anyone else has this problem or knows how to fix it.
Here is an image of what it looks like: http://fs5.directupload.net/images/160928/ud8opwig.jpg

I looked up the errorlog file on my host and it stated the following error:
PHP Fatal error: Call to undefined function wp_raise_memory_limit()
I searched for the function in wp-includes/functions.php but couldnt find it so I tried to replace that file from a new WordPress but now I get an Error 500 when trying to access my sites Backend.
Any ideas?
Update: Doing a manual update of WordPress like it is suggested here didnt solve the problem http://wordpress.stackexchange.com/questions/238043/admin-blank-page-with-working-front-end-after-updating-to-wordpress-4-6
Console still says:
https://mywebsite/wp-admin/load-scripts.php?…ery-core,jquery-migrate,utils,underscore,wp-util,wp-a11y,updates&ver=4.6.1 Failed to load resource: the server responded with a status of 400
When trying to access this url I get the following screen in google chrome
