Smod can't delete msg

[BiZiMDiYaR]

Hi,

Suddenly my smod can't delete any messages from the forum and she is getting a forum mysql error... but nothing changed, so what is causing this.. ? Can anybody help with this ? Al settings are normal... nothing special.. just happend with that 1 person, she has tried to delete from 4 different PC's... so should not be the problem on her side I assume. Does anybody have more info on why...

Thanks.
