For the side columns to show in "new posts" the search box in the available settings needs to be checked.
Instructions to manually select where the USC will display. This came with the USC files, I don't know how I missed it the first time.
1. Disable the automatic edits in the vBOptions > USC Options > Column Start Point.
2. In the template that you wish to start your columns, add the following code:
<!-- USC footer edit start -->
<table width="100%" cellpadding="0" cellspacing="0" border="0"> <tr> $usc_left <td
valign="top" width="100%">
<!-- USC footer edit end -->
3. In the template that you wish to end your columns, add the following code:
<!-- USC footer edit start -->
</td>
$usc_right
</tr>
</table>
<!-- USC footer edit end -->
If you are ending your columns in the footer, ensure that the closing code as above is placed before <if condition="$show['dst_correction']"> If you place it anywhere after this then it will affect the functionality of your forums.
