1- go to you "FORUMHOME" template
2- look for the the following code:
<tr align="center">
<td class="thead"> </td>
<td class="thead" width="100%" align="$stylevar[align=left]">$vbphrase[forum]</td>
<td class="thead" width="175">$vbphrase[last_post]</td>
<td class="thead">$vbphrase[threads]</td>
<td class="thead">$vbphrase[posts]</td>
<if condition="$vboptions['showmoderatorcolumn']">
<td class="thead">$vbphrase[moderator]</td>
</if>
</tr>
3- if it there remove it and save the template. if it not there just let the template as it is without any changes.
4- go to "forumhome_forumbit_level1_nopost" template
5- find the following code:
<tr align="center">
<td class="thead"> </td>
<td class="thead" width="100%" align="$stylevar[align=left]">$vbphrase[forum]</td>
<td class="thead" width="175">$vbphrase[last_post]</td>
<td class="thead">$vbphrase[threads]</td>
<td class="thead">$vbphrase[posts]</td>
<if condition="$vboptions['showmoderatorcolumn']">
<td class="thead">$vbphrase[moderator]</td>
</if>
</tr>
6- if it there, replace it with the following:
<tr align="center">
<td class="thead" width="5%"> </td>
<td class="thead" width="50%" align="$stylevar[align=left]">$vbphrase[forum]</td>
<td class="thead" width="25%">$vbphrase[last_post]</td>
<td class="thead" width="10%">$vbphrase[threads]</td>
<td class="thead" width="10%">$vbphrase[posts]</td>
<if condition="$vboptions['showmoderatorcolumn']">
<td class="thead" width="0%">$vbphrase[moderator]</td>
</if>
</tr>
and save. and it's done.
if it not there just add it exactly after the following code:
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
then save and it's done
