Problem with last post in thread

[roundhost]

I used mod_rewrite all over my forum and it may have effected my lastpostinthread links, where if you click the username it goes to another persons profile.

The code in the template is as follows:

<if condition="$show['lastpostinfo']">
<div class="smallfont" align="$stylevar[left]">
	<div style="clear:both">
		<if condition="$show['icon']"><img class="inlineimg" src="$icon[iconpath]" alt="$icon[title]" border="0" /></if>
		<a href="$vbphrase[site_url]newpostinthread$lastpostinfo[lastthreadid].html" title="<phrase 1="$lastpostinfo[lastthread]">$vbphrase[go_first_unread_in_thread_x]</phrase>"><strong>$lastpostinfo[trimthread]</strong></a> 
	</div>
	<div<if condition="is_browser('ie', 6)"> style="float:$stylevar[left]"</if>>
		<phrase 1="$vbphrase[site_url]lastposter-$lastpostinfo[forumid].html" 2="$lastpostinfo[lastposter]">$vbphrase[by_x]</phrase>
	</div>
	<div align="$stylevar[right]">
		$lastpostinfo[lastpostdate] <if condition="!$show['detailedtime']"><span class="time">$lastpostinfo[lastposttime]</span></if>
		<a href="$vbphrase[site_url]lastpostinthread$lastpostinfo[lastthreadid].html"><img class="inlineimg" src="$stylevar[imgdir_button]/lastpost.gif" alt="$vbphrase[go_to_last_post]" border="0" /></a>
	</div>
</div>
<else />
<div class="smallfont" align="$stylevar[right]">
	$lastpostinfo[lastpostdate] <if condition="!$show['detailedtime']"><span class="time">$lastpostinfo[lastposttime]</span></if>
	<a href="$vbphrase[site_url]lastpostinthread$lastpostinfo[lastthreadid].html"><img class="inlineimg" src="$stylevar[imgdir_button]/lastpost.gif" alt="$vbphrase[go_to_last_post]" border="0" /></a>
</div>
</if>

Can anybody see any problems? the mod_rewrite works fine, just goes to the wrong profile yet i do not beleive i changed any of the acctual code...

Thanks in advance,
