BuddyPress.org

I’ve discovered that if I access the page outside the scope of buddypress and wordpress (that is, accessing to the direct link without passing by my website) the thing returns a correct result for the friends (if I hardcode the input of course).
What could this mean? I require_once in my index wp-config.php and also in my friend_page (which is loaded on top of the index, in a slider that comes down). Is there a problem with this approach?
