need to fix forum bug

I have a vbulletin mod for (vb version 3.8.x), which works fine, apart from when a search is performed in the forum, there is a mysql db error. "Error Number : 1064" When I disable this mod, the search feature works fine. Need a vbulletin expert to fix the bug please. I can't provide you access to my admin, so you'll have to install the mod to your own vB 3.8.x test forum. (i.e. the mod which is causing the search error). Thanks!
