Database error

[ExTincTi0N]

Okay, my clients site is getting a db error whenever you go to a certian forum, same for when you click on a members name.

At first i thought it was vbseo for vb 4 but after doing a fresh install and turning the plugin off it still happens.

Also the site was using a different version of vb untill her old webmaster upgraded it to 4.

Forum db error:
