Radera "Du var senast här"

Jag har försökt via koden radera "Du var senast här" ett bra tag nu, kanske kan någon hjälpa mig? Orginalkoden för punBB 1.2 för den här delen:

// START SUBST - <pun_status>
if ($pun_user['is_guest'])
    $tpl_temp = '<div id="brdwelcome" class="inbox">'."\n\t\t\t".'<p>'.$lang_common['Not logged in'].'</p>'."\n\t\t".'</div>';
else
{
    $tpl_temp = '<div id="brdwelcome" class="inbox">'."\n\t\t\t".'<p class="conl">'.$lang_common['Logged in as'].' <strong>'.pun_htmlspecialchars($pun_user['username']).'</strong><br />'.$lang_common['Last visit'].': '.format_time($pun_user['last_visit']);

    if ($pun_user['g_id'] < PUN_GUEST)
    {
        $result_header = $db->query('SELECT COUNT(id) FROM '.$db->prefix.'reports WHERE zapped IS NULL') or error('Unable to fetch reports info', __FILE__, __LINE__, $db->error());

        if ($db->result($result_header))
            $tpl_temp .= '<br /><strong><a href="admin_reports.php">There are new reports</a></strong>';

        if ($pun_config['o_maintenance'] == '1')
            $tpl_temp .= '<br /><strong><a class="showhot" href="admin_options.php#maintenance">Maintenance mode is enabled!</a></strong>';
    }

    if (basename($_SERVER['PHP_SELF']) == 'index.php')
        $tpl_temp .= '</p>'."\n\t\t\t".'<p class="conr"><a href="search.php?action=show_new">'.$lang_common['Show new posts'].'</a><br /><a href="misc.php?action=markread">'.$lang_common['Mark all as read'].'</a></p>'."\n\t\t\t".'<div class="clearer"></div>'."\n\t\t".'</div>';
    else if ($_SERVER['QUERY_STRING'] == 'action=show_new')
        $tpl_temp .= '</p>'."\n\t\t\t".'<p class="conr"><a href="misc.php?action=markread">'.$lang_common['Mark all as read'].'</a></p>'."\n\t\t\t".'<div class="clearer"></div>'."\n\t\t".'</div>';
    else
        $tpl_temp .= '</p>'."\n\t\t\t".'<div class="clearer"></div>'."\n\t\t".'</div>';
}

$tpl_main = str_replace('<pun_status>', $tpl_temp, $tpl_main);
// END SUBST - <pun_status>
