Re: No 404, Just Shows
I think the problem here is that it’s installed in a sub directory. My guess is that if this is BP’s fauly, it’s hijacking the path and the 404 template page never gets triggered. Let me do some more digging tonight and see if I can patch this.
Otherwise I’d say this might just be WPMU.
As a general rule, WPMU doesn’t really like to be installed in a subdirectory off of the root of the domain.
I.E
domain.com/wpmu/member is bad
domain.com/member is good
Chances are this isn’t a BP issue at the core, but rather a WPMU issue. Worth looking into though.
