Database error

[Ninth Dimension]

I'm not sure if this is the correct forum or not, but here goes..

I'm getting a database error generated when someone visits my site. This specific person has been banned, but I guess he does not know it yet (i.e. he keeps coming back), so I'd like to try and fix the problem.. here is the error:

I'm using vBadvance as my front page, so I'm guessing it's an error with that, but I've never been too good with MySQL errors, so if you could point me in the right direction. thank you
