BuddyPress.org

Hello,
I have create a new site, with BP and BP Members only because i wanted to validate the subscription. But it don’t work correctly.
I receive the email confirmation subscription but when i want to log as a user test, i entry my pseudo and password, it’s validate, but i don’t go to the site but to the page log-on of wordpress, as if i have to be a subscriber of wordpress. It’s not normal.
I try first to install Theme my login, but the registration page (name “register”) is in conflit with the register page native on BP (name “inscription”).
I don’t see what doesn’t matter !
Sorry for my english… I’m french.
