Secure Pages Causes AJAX on UC Credit Card Module (Checkout time) to Fail

I'm getting the same thing, the Credit Card module's AJAX bar on the Checkout Page (Ubercart) fails to load when I enable Secure Pages with "Switch back to http pages when there are no matches" checked. Uncheck this and the Credit Card Payment details loads fine.

Opening it in Chrome's debugger shows a resource error, something about the credit card is mentioned (I can dig up this error message later).

The workaround above to add another payment option does not work for me, and I've also tried turning on Clean URL's which also did not work.

A related post I've found:
http://www.ubercart.org/forum/support/9821/security_error_ssl_checkout_page

Please help! I can provide more details and set up a dev server replicating the issue if needed.

A ha! Thank you forums. I made this change to my "Pages" area of Secure Pages:

cart/checkout
cart/checkout/review
cart/checkout/payment_details/*
cart/checkout/complete

This is a workaround from :
http://www.ubercart.org/forum/support/3380/failing_ajax_call_checkout_ssl

Closing the issue for now, later I will need to add in admin* and user* to secure the administration and user pages.

Opening again- it seems like Secure Pages + SSL is essential for an Ubercart setup taking credit cards. As it does not work with the Credit Card module out of the box, we should revise the default "Pages" settings to include the following:

cart/checkout
cart/checkout/review
cart/checkout/payment_details/*
cart/checkout/complete

Or, a note should be put on the Secure Pages module page pointing people using Ubercart Credit Cards to use these settings.

I had the same issue, i simply moved

<script type="text/javascript" src="/<js dir>/jquery-1.5.2.min.js"></script>
<script type="text/javascript" src="/<js dir>/jquery.validate.js"></script>

further up the js list which fixed my issue, funny enough worked fine without SSL
