# wp-admin blank (or Error 404)

 * 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/](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](http://www.techzoomin.com/wordpress-login-issueswp-admin-showing-404-error-page/).
   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](http://wordpress.org/support/topic/plugin-w3-total-cache-how-to-uninstall-with-no-admin-panel).
   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!
