DB error

[محروم.كوم]

I'm getting loads of these errors, tried to solve this by posting a ticket to vb, who told me the error was on the server side. Contacted my host who didn't see any errors on their side.
BTW there is no table named : "/tmp/#sql_2f4_5.MYI'" - not that I can find anyway!?
Any help would be much appreciated.

Code:
