Unfortunately we do not offer support for this mod at GlowHost. The offical thread where you downloaded the mod is where you can find support.

If it were me, I would start by using the default vbulletin theme to see if it works. If not you might have to disable some or all of your plugins and test it again. Then enable them one at a time until it breaks. Honestly, I am not sure it will work with 3.8, it was really built with 4.x in mind.
