 * 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](http://fs5.directupload.net/images/160928/ud8opwig.jpg)

 * I forgot: Disabling all Plugins and changing the theme doesnt solve the problem

 * Go to that page in Chrome. Hit f12. Click on console. That will show you that
   the style sheet is not loading. You need to add the missing style sheet.

 * 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?

 * Deleting the .htaccess file resolves the problem but then I cant access the frontend
   because I use RewriteBase for my WordPress Installation since its in a subdirectory
   of my domain.
 * This seems to be a problem with my Host, at least thats what I think
