JB007:
I don't think I understand what you mean by "past ...".
If you mean "Did I modified the ubb_library.pl as you instructed?", I think I did.
It all started when I tried to add the "Attachment File Manager v1.6" and failed to do the hack.
After failing to do so, I changed the modified cgi files back to the old ones without the "AFM v1.6" hack, and things started to go wrong.
It's strange that the other UBB board that I set up on the same win2k server is affected also, even though I didn't do anything on that board. I got the same error message from the other board.
It's really strange...
