Sirdude - Did you mean the UBB referer table? I just ran a search on it for anything with "site" in the string and really there was nothing related to site_id=1 at all.
Are you sure it would show up in there? For example when I look for "forums" in that same table I don't find any internal references, i.e. it's all external sites.
I'm still thinking this must be a link from within the UBB software, related to all the editors getting errors of "post not found" when they make a new post. But maybe they really are two separate problems.
