XF 1.5 Upgrade to 1.5.2 Failed

Since I got the PHP and MySQL upgraded last week finally, thought I would upgrade the forum tonight. Got everything uploaded in the forum folder fine and then went to do the upgrade on the site when I got this almost immediately after it started on http://www.gameogre.com/forums/install/index.php?upgrade/run

Failed to get controller response and reroute to error handler (XenForo_Install_Controller_Upgrade::actionrun)

An exception occurred: Undefined index: in /home/gameogre/public_html/forums/library/config.php on line 19

The forum is still up in debug mode somehow and I even see a new feature, but the upgrade wont complete. I uploaded it twice and the forum itself even tried to upload it once.

Anybody know what caused this and how it can be fixed?
