I am having trouble resolving an issue related to SSL and CSS background images.

If a page is loaded via https (like a login page), any images defined in CSS as a background image are still requested via http.   If you are looking at the page via Chrome, you get a nasty "mixed mode" error message.  I'm not sure how to fix it.

To easily replicate, SSL enable any page and try out the default Dark Knight skin for 6.0.  Look at the page with Chrome and you should see the nasty message.

Any ideas?

Thanks Cathal.
However, those don't solve the problem. After more research, I belive the problem is that DNN does not proerliy link the CSS files for skins and modules when the page is in SSL mode.

Looking at Firebug, I can see that all of the CSS files are being requested using standard http instead of https. I am pretty sure this must be a bug in DNN. I've logged in it Gemini.
