Disable required activation user BP

Hi, I'm trying to disable the require activation of new users registered by BP. I've tried using the following cose in functions.php, but it does not work. I want that administrators don't need to activate users. Can you help me please? PS. I'm using different registration forms (one for Students, one for Instructors). function disable_validation( $user_id ) { global $wpdb;   $wpdb->query( $wpdb->prepare( "UPDATE $wpdb->users SET user_status = 0 WHERE ID = %d", $user_id ) ); } add_action( 'bp_core_signup_user', 'disable_validation' );   function fix_signup_form_validation_text() { return false; } add_filter( 'bp_registration_needs_activation', 'fix_signup_form_validation_text' );
