have you checked for any errors in your web server’s error log? They might help by indicating where the problem is.

This seems a lot like a permission problem, have you done any other change lately? May be you can try to reset the permissions of your whole WordPress site folder?

If you have a recent backup, you could probably restore it and then try to update again. This would rule out the possibility that the upgrade itself has something to do with it.

Your requirements seem correct. Permissions depend on how you run PHP. For example, if you run PHP-FPM with NginX, you need to check which is the ‘user’ on the server, and make all those WP files readable and writable for him. This should be quite easy for the IT department, and should read something like:

chmod -R 755 *
chown -R user:user

Hm, it certainly looks like CSS not loaded properly. If browser cache clear doesn’t help, may be you should try it with another browser?

Also, if by any chance you have some caching enabled on your hosting side, you might want to clear that one as well.

You might also want to check your logfiles and see why it is failing. XAMPP log files by by default are kept at:

\xampp\apache\logs\error.log

Helloooooooooooooo, anybody here?

Here is how I solved the exact same problem:

— I must say that I installed the plugin & afterwards moved the site from a subfolder of the www to the www itself. That’s when the plugin stopped working. I can’t guarantee it will solve any other problem than moved wordpress ?

I checked permissions and this wasn’t the problem. So I started looking for symlinks, and here is what I found in the /home/www/wp-content folder:

70 Sep 2 12:31 advanced-cache.php -> /home/www/subfolder/wp-content/plugins/wp-cache/wp-cache-phase1.php

As I already said, the site was moved Out of the subfolder and placed into the main “www”. So I deleted the symlink and created it again:

~# rm –rf advanced-cache.php
~# cd /home/www/wp-content/plugins/wp-cache/
~# ln –s home/www/wp-content/plugins/wp-cache/wp-cache-phase1.php advanced-cache.php

This solved the issue and no problems experienced afterwards.

I hope it helps.
