Replace that code with something like this:
Code:
<tr align="center">
<td class="thead" width="30"> </td>
<td class="thead" align="$stylevar[left]" nowrap="nowrap">$vbphrase[forum]</td>
<td class="thead" width="275" nowrap="nowrap">$vbphrase[last_post]</td>
<td class="thead" width="150" nowrap="nowrap">$vbphrase[threads]</td>
<td class="thead" width="150" nowrap="nowrap">$vbphrase[posts]</td>
<if condition="$vboptions['showmoderatorcolumn']">
<td class="thead" width="150" nowrap="nowrap">$vbphrase[moderator]</td>
</if>
</tr>
