Protecting BuddyPress Pages

Hi Tom,

I have a membership site at christiangays.com. I'm using Simple Membership to protect my pages but it doesn't protect my BuddyPress pages, so on the support forums it was suggested that I add

add_action('bp_before_profile_loop_content', function(){
if (!is_user_logged_in()) {
echo '<p>'.__('Only Logged member can see member\'s profile.').'</p>';
return;
}
})

which I did, but it didn't work, so they have asked

You must at least see the message : "Only Logged member can see member's profile." when you are logged-out, UNLESS your buddypress theme does not support that filter/action.

Would you know?
