Problem with search function on vbulletin 4.

[RamdonGhai]

I upgraded my board to vb4.. Mostly everything was straight forward, but now the search feature is not working properly. When you try to run a search, its giving a database error. I checked the permissions on the ftp site for search.php, which was 755.

I want the search feature to work, or at least is there a way to put vb3 search feature back on (the users seemed to like the older one a lot more)

Are there any third party search options that could probably solve my problem? Maybe even run better than the built in search feature?

Thanks in advance!
