When i view your source (visiting your testing item links page), i see
HTML Code:
<head>
<base href="http://www.gamersvault.net/forum/" />
<!-- WoWHead Mouseover-Tooltips -->
<script src="http://www.wowhead.com/widgets/power.js" type="text/javascript"></script>
When i visit a thread w/ on my forum
HTML Code:
<head>
<!-- WoWHead Mouseover-Tooltips -->
<script src="http://www.wowhead.com/widgets/power.js" type="text/javascript"></script>
<!-- /WoWHead Mouseover-Tooltips -->
I think the template is SHOWTHREAD,
for example, my template is
HTML Code:
$stylevar[htmldoctype]
<html xmlns="http://www.w3.org/1999/xhtml" dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
$headinclude
...............
you have the base tag before the headerinclude, which is causing the problem.
