 * Attempted to restore through the plugin but the site crashed with:
 * Warning: require_once(/home/content/16/10111516/html/wp-content/db.php) [function.
   require-once]: failed to open stream: Numerical result out of range in /home/
   content/16/10111516/html/wp-includes/load.php on line 331
 * Fatal error: require_once() [function.require]: Failed opening required ‘/home/
   content/16/10111516/html/wp-content/db.php’ (include_path=’.:/usr/local/php5_3/
   lib/php’) in /home/content/16/10111516/html/wp-includes/load.php on line 331
 * Tried a manual restore via file manager and encountered the same errors.
 * Running latest version of the plugin and wordpress. Site was working fine prior
   to restore, I was only trying to roll back a theme update.
 * Any help greatly appreciated

 * Hi,
 * If you have a file wp-content/db.php, then it sounds like you have WP Total Cache
   installed. That’s very broken in WordPress 3.5.1 – see the vote count on the 
   WP Total Cache plugin page. It’s breaking all kinds of plugins in all kinds of
   exotic ways, but it’s not something controllable/fixable from inside the plugins
   themselves.

 * Here’s a thread in the W3 Total Cache forum – seems that it’s breaking everyone’s
   backup plugins, left, right and centre… [http://wordpress.org/support/topic/w3-total-cache-and-backup-buddy?replies=24#post-3973003](http://wordpress.org/support/topic/w3-total-cache-and-backup-buddy?replies=24#post-3973003)
