Try:

$forumbits
<tbody>
    <tr>
        <td class="tfoot" align="center" colspan="<if condition="$vboptions['showmoderatorcolumn']">6<else />5</if>"><div class="smallfont"><strong>
            <a href="forumdisplay.php?$session[sessionurl]do=markread" rel="nofollow">$vbphrase[mark_forums_read]</a>
            <if condition="$vboptions['forumleaders']">&nbsp; &nbsp;
            <a href="showgroups.php$session[sessionurl_q]">$vbphrase[view_forum_leaders]</a></if>
        </strong></div></td>
    </tr>
</tbody>
</table>
