CMS Invalid path after installing CMS widget?
 

I recently enabled CMS in vBulletin 4.06 Suite (skipped a few versions and just used the forums waiting for some of the bugs to be fixed).

Today, I tried to add this widget and after I do I get a path error: Fatal error: Class 'vBulletin' not found in /path/to/forum/packages/vbcms/widget/execphp.php.

I recently moved to a new dedicated server. What's showing in the error message is the correct path for my old server but incorrect for the new. It's odd because everything is working fine until I try to add the widget.

Where is this information stored or how do I change this?
