Curious - is this happening to any users that have come to your board since you installed the hack originally? If so, you are most likely seeing the same issue I am. I have to run an UPDATE query something like
Code:
UPDATE vb_user SET 'money' = 0.00 WHERE 'money' IS LIKE 'NULL';
- I'm guessing off the top of my head, but I have to do this ever so often or the new users don't get anything.
