   My site was working just fine until today when I tried to access /wp-admin and got a completely blank page. I searched for 45 minutes or so for people with similar problems. Here are things I tried:

   • Remove plugins folder
   • Download a fresh copy of WP and upload everything to the server (except wp-content)
   • delete .htaccess (got a weird error saying "Multiple Connections" so I put it back)
   • Double checked includes.php to make sure there wasn't any leading or trailing space

   I found a suggestion to include the .php file entension like so: /wp-admin.php. This at least got me an Error 404 page, which is something, but I still can't access the WP backend. I did some searching to find out how to fix this problem, and found many of the same solutions I tried above to no avail.

   Any help would be appreciated. I've got a client who needs to start writing posts today and I don't want to flub up his install!

   Oh, I also tried:

   • Deleting browser cache
   • Setting permissions to 755 (http://www.techzoomin.com/wordpress-login-issueswp-admin-showing-404-error-page/)
   • Renaming the theme so WP would default to twentyeleven (this resulted in every page being blank)

   I had a similar situation occur recently when I tried to access the admin panel of a client’s website after upgrading to WordPress 3.2.1, and it was indeed frightening!

   Fortunately, the fix was incredibly simple: I just had to go into CPanel and change the permissions on the wp-admin folder to 755 as described in this post. Do the same for wp-content and wp-includes if they are not already set to 755 (mine were). The individual files within these directories should be set to 644 already, but you can spot check those just to make sure.

   The other thing I did (not counting troubleshooting like disabling all of the plugins, etc.) before trying the above was to remove the W3 Total Cache plugin as described here. This likely wasn’t necessary but since I had read about this plugin having conflicts with the latest version of WordPress, I tried it just in case. Note that you must remove not only the W3 Total Cache folder under Plugins (wp-content/plugins/w3-total-cache/) but also all of its associated files:

   wp-content/advanced-cache.php
   wp-content/db.php
   wp-content/object-cache.php
   wp-content/w3tc/
   wp-content/w3-total-cache-config.php
   wp-content/w3-total-cache-config-preview.php
   wp-content/plugins/w3-total-cache/

   You may be able to resolve your problem simply by changing the file permissions, so try that before resorting to removing the W3 Total Cache plugin files.

   Hope that helps, and good luck!
