Just installed SSL - "page contains both secure and nonsecure items"

Would someone go to www.aspenshopsonline.com/index.php?main_page=login and advise me why I am getting the "This page contains both secure and nonsecure items" popup in IE?
Note that if you select Yes to the prompt to display nonsecure items that I get an "Error on page" message in the bottom margin of the browser. This message does not appear if I select not to show nonsecure items.
I just activated SSL on my site and this is what I am running in to.

I followed the instructions for activating SSL per "How do I enable SSL after I have installed Zen Cart? " tutorial.

I can't seem to find what items are non-secure here.
