So you mean this is how the forumdisplay template should look like, right?
Code:
<vb:if condition="$show['stickies']">
<ol id="stickies" class="stickies">
{vb:raw threadbits_sticky}
</ol>
</vb:if>
<div class="threadbit">
<p class="nonthread">
<-- AD CODE HERE -->
</p>
</div>
<vb:if condition="$show['threads']">
<ol id="threads" class="threads">
{vb:raw threadbits}
</ol>
</vb:if>
