[ Closed ] Bug in extern.php

Option "online_full" doesn't work.

See code below from "extern.php":

    echo $lang_index['Guests online'].': '.forum_number_format($num_guests).'<br />'."\n";

    if ($_GET['action'] == 'online_full')
        echo $lang_index['Users online'].': '.implode(', ', $users).'<br />'."\n";

into "lang/English/index.php" I can't find rows:

'Users online'                    =>    'Users online',
'Guests online'                    =>    'Guests online',
