Umm, all others redirecting are ok, only this.
I've changed the option Url forum and Url Index in http://www.mysite.com/vbulletin, but the problem remain.

In vbulletin-style.xml on line 24944:

<noscript>
<meta http-equiv="Refresh" content="2; URL=$url" />
</noscript>

<script type="text/javascript">
<!--
function exec_refresh()
{
window.status = "$vbphrase[redirecting]" + myvar;
myvar = myvar + " .";
var timerID = setTimeout("exec_refresh();", 100);
if (timeout > 0)
{
timeout -= 1;
}
else
{
clearTimeout(timerID);
window.status = "";
window.location = "$js_url";
}
}

var myvar = "";
var timeout = 20;
exec_refresh();
//-->
</script>

The address $url e $js_url are ok, in all others cases, admincp redirecting too, but in case of a notice of passwords expired, it redirects at root of the site.

It seems to me a structural problem, (a bug).
