BuddyPress.org

Hello everyone

I’m having some issues over here trying to configure buddypress using multisite instance from wordpress
My problems is

I have this main page
http://www.mysite.com/members/admin
And it works

But in one of my subdmains that is
fr-ca.mysite.com/members/admin
I get an 404 page from wordpress

I would like to understand how those this member and member edition works
So I can try to replicate it.

Because for the first time I didn’t changed anything realated to this to make this part work
This is the default theme from buddypress

Does anyone know how to help me on this?

PS: I get 404 page if I go to:
fr-ca.mysite.com/register
fr-ca.mysite.com/member
fr-ca.mysite.com/member/name
fr-ca.mysite.com/member/name/profile/edit/group/1
fr-ca.mysite.com/activate

All those works on the http://www.mysite.com

Thanks,
Thiago Cruz
