I set up SSL (https) to forward all access to http pages with the form to https pages with the form. I would like to use SSL with the form pages only. But when I access the pages, it shows the warning message “This page contains both secure and nonsecure items. Do you want to display the nonsecure items?”. I don’t know what to modify.

What I know is that I should change HTTP links to HTTPS links in the page but I cannot figure out how. I ran Fiddler and found that HTTP links to theme css file, theme image files (gif, jpg), theme js file and dd-formmailer.php?v=1 existed. But I don’t know which files to modify..

I asked support to Dagon Design but they were not familiar with SSL..
