Nonsecure items at checkout success page

Hi,

After successful checkout, there is a warning popped up saying "this page contains both secure and nonsecure items. Do you want to display the nonsecure items?" What is causing this? As far as I know all the pictures are within the zencart. Any suggestion? Please advise. Thank you.

Thanks. I thought it was the google translation. But after removing it, I still get the nonsecure alert.

<<Have you checked the location of every file thats being called? Especially images?>>

Yes, I checked every possible thing. I don't have google analytics nor click counter. All the images don't have http.

The sideboxes aren't the problem either because when I click on my account page which is secured, I didn't get any nonsecure alert. The account page uses the same sideboxes, header menu, logo and footer. I even tried deleting checkout success message. It still doesn't make a difference. I find this very strange.

Yep... that's odd... I placed an order and can't see anything in there that would do that...

Would your server's error log tell you?

Is it possible to make checkout success page a non-secured page to solve this problem? How do I do that?

Is checkout success page currently not secure?
I thought that error message comes when you move from secure to non-secure(https to http)

The nonsecure alert is a warning rather than an error though.

The checkout success page is currently secure but I thought if I could make it not secure, the alert message which says "this page contains both secure and nonsecure items" might not show up.
