In Forum Home templates group in both templates...
forumhome_forumbit_level2_post
forumhome_forumbit_level1_post
Find and delete:
Code:
<td class="alt1">$forum[threadcount]</td>
<td class="alt2">$forum[replycount]</td>
Save. Then in FORUMHOME template find and delete:
Code:
<td class="thead">$vbphrase[threads]</td>
<td class="thead">$vbphrase[posts]</td>
That will remove your thread and post columns.
