Problem:
Registered user tried to post a reply
to a thread and UBB told them:

"Sorry, we could not post your reply to this topic. Contact your bulletin board administrator and inform them that they may have may run out of available disk space. Their web host may be preventing them from posting new files. "

We have abundant disk space so that is not
the cause of the problme. Why is UBB generating this message? How do I fix the
problem?

It has only been reported by one person.

Thanks for your help.
