When i view your page while logged in, IE is using quirks mode which uses the IE 5 rendereing engine.
in the source, the CMS inline script is above the doctype tag.
I am not able to access your files through FTP, so i cant see the code, but it looks like you have skipped step 3 of the Design Extneder Update instructions:
which is to locate the following code on your pages:
<?php require_once("WA_CMS/WA_CMS.php"); ?>
and move it to be within the head tags.
