BuddyPress.org

Hi!

I’m using WPMU (latest) and Buddypress (latest, not trunk) + automattics P2 microblogging theme (latest).

Objective: I’ve got two blogs besides BP and the second one is for all the users. The first is a root-blog and only intended for non-members who perhaps want to become members. It’s a closed website and non-members cannot see the second blog.

When using the P2-theme (second blog) I need to have all users have the role “author”. But when signing up the users only get the author-role for the primary root-blog and not the secondary. I’ve tried to use a wpmu-plugin (just some text) which uses this code:

(from here: http://mu.wordpress.org/forums/topic/13675?replies=12#post-83298 )

add_action( 'wpmu_new_user', 'ds_new_user_meta', 10, 2);

function ds_new_user_meta($user_id) {

add_user_to_blog('1', $user_id, 'subscriber');

}

This code seemingly works for others users but gives me this error message with buddypress:

Warning: Cannot modify header information – headers already sent by (output started at /home/xxxxx/public_html/xxx.com/wp-content/mu-plugins/new-user.php: in /home/xxxxx/public_html/xxxxx.com/wp-content/plugins/buddypress/bp-xprofile/bp-xprofile-signup.php on line 5

What’s wrong?
