There is a failure in the instructions:
Point 2.1 is wrong.
CHANGE THIS:
Step 2.1: Find this line (at line 10):
$ubbt_lang[$box]
And CHANGE it into this:
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td colspan="2" class="tdheader">
<b>$ubbt_lang[$box]</b>
</td>
<td align="right" valign="bottom" class="tdheader">
<table border="0" class="tablesurround">
<tr>
<td class="navigation" nowrap="nowrap">
<!-- prevoption is either previous.gif or greyprevious.gif -->
$prevstart
<img src="{$config['images']}/$prevoption" alt="{$ubbt_lang['PREV_PAGE']}" border="0" {$images['previous']} $imagestyle />
{$ubbt_lang['PREV_ICON']}
$prevstop
</td>
<td class="navigation" nowrap="nowrap">
<a href="{$config['phpurl']}/login.php?Cat=$Cat">
<img src="{$config['images']}/all.gif" alt="{$ubbt_lang['FORUM_IND']}" border="0" {$images['all']} $imagestyle />
{$ubbt_lang['INDEX_ICON']}
</a>
</td>
<td class="navigation" nowrap="nowrap">
<!-- nextoption is either next.gif or greynext.gif -->
$nextstart
<img src="{$config['images']}/$nextoption" alt="{$ubbt_lang['NEXT_PAGE']}" border="0" {$images['next']} $imagestyle />
{$ubbt_lang['NEXT_ICON']}
$nextstop
</td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
TO:
Step 2.1: Find this line (at line 10):
$ubbt_lang[$box]
And CHANGE it into this:
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td colspan="2" class="tdheader">

{$ubbt_lang['PREV_ICON']}
$prevstop
</td>
<td class="navigation" nowrap="nowrap">
<a href="{$config['phpurl']}/login.php?Cat=$Cat">

{$ubbt_lang['NEXT_ICON']}
$nextstop
</td>
</tr>
</table>
</td>
</tr>

then it is working.
The table tag is closed three times. Does not matter if you have no menues beside your forum but I have the sidebar hack installed and then this kills the layout
Please update the documentation!
