# W 3 Total Cache causing 500 Internal Server Error

 * Just updated to the latest version of WordPress, and noticed the update made 
   it run a lot slower on the front end. So I went into the W 3 Total Cache plugin
   to check the settings. The moment I ran the auto-install portion of w3tc (pink
   box on the top), I got a 500 Internal Server Error. Front end is 500 internal
   server error, and so is the backend WP dashboard.
 * Did some forum searching, and the creator of the plugin suggested the following
   [in this thread](http://wordpress.org/support/topic/plugin-w3-total-cache-500-internal-server-error?replies=40)(
   which is now closed):

   >  (

   > cache-config.php (if you want) (3) Then rename or delete wp-content/plugins/
   > w3-total-cache/ if you still have any issues accessing WP Admin and reinstall
   > once you can login again (and rename it back if you have)
 * **1. **I made sure the public_html folder was chmod 777 and replaced the .htaccess
   file to the default:
    contents: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine
   On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME}!-
   d RewriteRule . /index.php [L] </IfModule>
 * # END WordPress
 * **2. ** I deleted the db.php, object-cache.php, advanced-cache.php and w3-total-
   cache-config.php files from my FTP server.
 * **3. **I deleted the w3-total-cache folder from wp-content
 * So I did all of the above, but still I’m getting 500 internal server error. Can’t
   bring up my website or login to the backend dashboard. Not sure what the best
   route is to get my site back up and running.
 * Any clues where to go with this?
