New zip file uploaded with the errant code removed - that google ads code only appeared in the postpit_legacy template - just delete this bit from that template
HTML Code:
<script type="text/javascript"><!--
// XHTML should not attempt to parse these strings, declare them CDATA.
/* <![CDATA[ */
window.googleAfmcRequest = {
client: 'ca-mb-pub-xxxxxxxxxxxx',
format: '320x50_mb',
output: 'html',
slotname: 'xxxxxxxxxxxxxxx',
};
/* ]]> */
//--></script>
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_afmc_ads.js"></script>
or import new XML in the zip I just uploaded (1.0.3a)
