Classifieds: JavaScript not forwarding page location

The JavaScript redirects are not working on our install of this; I see the message "You are being redirected. Please wait." with a loading bar that never redirects. This behavior happens on the My Credits page when I click on the "Purchase" button, and on the member main Classifieds tab (/members/username/classifieds/). Also, the jQuery on the Saved Ads display buttons is not working.

On the My Credits > Purchase button click, the loading page fails to execute immediately after this line: <script type="text/javascript">//<![CDATA[ window.location = 'http://example.com/checkout/'; //]]></script>
