Hi there, I am not a programmer at all and don't have any knowledge of how PHP works. However, in using the BuddyPress Courseware plugin this error message continuously comes up on group pages under the menu option labeled Courseware:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/content/92/10013292/html/wp-content/plugins/buddypress-courseware/roles/roles.class.php on line 269

Warning: Invalid argument supplied for foreach() in /home/content/92/10013292/html/wp-content/plugins/buddypress-courseware/roles/roles.class.php on line 271

Please help!

I figured same problem by doing so (with get_teachers( $group_id ) function):

function get_teachers( $group_id ) {
    $teachers = array();

    $group_admins = groups_get_group_admins( $group_id );
    $group_members = groups_get_group_members( $group_id );
    //$group_members = array_merge( $group_admins, (array)$group_members['members'] );

    if (isset($group_members['members']) and !empty($group_members['members']))
        $group_members = array_merge( $group_admins, (array)$group_members['members'] );
    else
        $group_members = array_merge( $group_admins, array() );

    foreach ( $group_members as $member )
        if( self::can_teach( $member->user_id ) )
            $teachers[] = $member->user_id;

    return $teachers;
}
