The phrase "displaying content with security certificate errors" is confusing to me. Is it saying that thecontent has certificate errors? Isn't the certificate associatedwith the website itself, not with content. So, assuming that the warning has to do with the website's certificate, what should I look for as being in error? I display the certificate by clicking the lock icon (security report). Nothing I see there indicates any sort of error or problem. Under Certification Path/Certificate status it shows "This certificate is OK."
The site is defined as trusted un Tools/Internet Options; however, at the bottom of the page it shows a green check and "Unknown Zone (Mixed)". Is this merely another manifestation of the certificate problem?
Nothing I've read in the IE help nor in any of the discussions here tells me how to fix the problem.
I'm new to IE8, having just installed today. Several other sites get this same error message -- all of them ones that had no problem under IE6.
