# Undefined variable (across multiple document), upon upgrade

 * I have over 10 blogs running all with 2.5.1. I followed the instructions for 
   each and made certain to turn off my plug-ins before doing the upgrade.
 * However, when I started to upgrade the last one, I started to receive errors 
   all over the place (published on the live page and throughout the dashboard).
 * I have since removed non-default plugins and deactivated those that come with
   the original install. I attempted to re-install EVERYTHING, with a fresh copy
   and I still am receiving “undefined variable” errors across the site, such as:
 * Notice: Undefined variable: toggle in /var/www/vhosts/mix1037fm.com/httpdocs/
   blog/mixmorning/wp-admin/plugins.php on line 154
 * Notice: Undefined variable: plugin_info in /var/www/vhosts/mix1037fm.com/httpdocs/
   blog/mixmorning/wp-admin/plugins.php on line 141
 * Notice: Undefined index: m in /var/www/vhosts/mix1037fm.com/httpdocs/blog/mixmorning/
   wp-admin/includes/post.php on line 518
 * Notice: Undefined index: cat in /var/www/vhosts/mix1037fm.com/httpdocs/blog/mixmorning/
   wp-admin/includes/post.php on line 519
 * I just don’t know where to start as a fresh install of wordpress isn’t fixing
   anything. Is there something wrong with my database?

 * PHP is set up to display notices.
