Hello,

Please use the following code. It will send email notification to all group members on new activity update,

function buddydev_mail_on_new_group_activity( $user_ids, $args ) {

	if ( empty( $user_ids ) ) {
		return;
	}

	$user_emails = array_map( function ( $user_id ) {
		$user = get_user_by( 'id', $user_id );

		if ( ! $user ) {
			return;
		}

		return $user->user_email;
	}, $user_ids );

	$user_emails = array_filter( $user_emails );

	if ( ! $user_emails ) {
		return;
	}

	$group                      = new BP_Groups_Group( $args['group_id'] );
	$loggedin_user_display_name = bp_get_loggedin_user_fullname();

	$activity = new BP_Activity_Activity( $args['activity_id'] );

	$activity_content   = $activity->content;
	$activity_permalink = bp_activity_get_permalink( $activity->id, $activity );

	$subject = sprintf( '%1$s posted to %2$s', $loggedin_user_display_name, $group->name );

	$message = <<<MAIN
Hi,
	
{$loggedin_user_display_name} posted...
	
{$activity_content}

Link: {$activity_permalink}
MAIN;

	wp_mail( $user_emails, $subject, $message );
}
add_action( 'bp_group_activities_notify_members', 'buddydev_mail_on_new_group_activity', 10, 2 );

Please do let me know if it works or not.

Ravi

Hello Carsten,

Thank you for posting. Is there any chance you have created member types manually using some custom code. Please have a look at your bp-custom.php and current theme function file for such custom code.
