ONE LAST UPDATE:
I may have figured out the problem. The board that was causing this error message was a "read posts only" board for Registered Users -- they could not post or reply. Only Administrators could post message and attachements.
However, when a Registered user would go there and successfully read the post they could not read the attachment. I have "fixed" the problem by giving everyone Read/Write access to this board.
HOWEVER, this is not what I would like for this board.
Is there a way to change it so a board can be "read access" only to Registered users and this read access to include attachments as well?
