Figured out the problem you need to change
Code:
<td class="catnav" id="threadbookmark" nowrap="nowrap">
<a href="$show[nojs_link]#goto_threadbookmark">Bookmark</a>
<if condition="$show['popups']"><script type="text/javascript"> vbmenu_register("threadbookmark"); </script></if>
</td>
to
Code:
<td class="vbmenu_control" id="threadbookmark" nowrap="nowrap">
<a href="$show[nojs_link]#goto_threadbookmark">Bookmark</a>
<if condition="$show['popups']"><script type="text/javascript"> vbmenu_register("threadbookmark"); </script></if>
</td>
catnav needs to be changed to vbmenu_control for vB 3.6.8 not sure if this is different for other versions but that fixed my problem

incase anyone else is having that same error I did where the background would be black.
