I think maybe one way to fix it is to have a .htaccess file that redirects everyone to one or the other (if that is in fact the problem). I don't know a lot about .htaccess files so I don't know how to tell you to do it, but I I've seen it mentioned here before so I think if you search you can find it.

I did a search on that error, and I think it's also possible to add an http header to allow access to other urls, but that's probably a little harder to do.
