Hi
I used this in 4.2.2 it used to work nicely.
You can copy and paste this in both arcade and arcade_vb4 templates
HTML Code:
{vb:stylevar htmldoctype}
<html xmlns="http://www.w3.org/1999/xhtml"<vb:if condition="$vboptions['enablefacebookconnect']"> xmlns:fb="http://www.facebook.com/2008/fbml"</vb:if> dir="{vb:stylevar textdirection}" lang="{vb:stylevar languagecode}" id="vbulletin_html">
<head>
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="-1" />
<meta http-equiv="Cache-Control" content="no-cache" />
<title>{vb:raw ibprotitle}</title>
{vb:raw headinclude}
{vb:raw headinclude_bottom}
</head>
<body>
{vb:raw header}
{vb:raw navbar}
<div class="blockbody">
<div class="blockrow">
{vb:raw arcadeheader}
{vb:raw maincontent}
</div>
</div>
{vb:raw footer}
</body>
</html>
