I receive the same error, which probably means the file for the rules was lost in transit somewhere. It is supposed to work (and it returns a general rule list for the site), but it appears that the file it's supposed to lead to is missing.
ah, okay. I've attempted to contact the board admin through the e-mail provided. although I had a feeling it may be overlooked due to my status of a new member, so I also posted here for good measure. Should I PM somebody in charge or should this suffice for now?
