Getting 'Connection is Untrusted' error on secure site with a valid SSL certificate. The site is elearning.louisville-redcross.org. Error comes up when I click 'Confirm' button on registration page. Tested site on IE, Opera, and Safari--no problems.
Here is the complete error message:
This Connection is Untrusted
You have asked Firefox to connect securely to elearning.louisville-redcross.org, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to
this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
Technical Details elearning.louisville-redcross.org uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)
I Understand the Risks
If you understand what's going on, you
can tell Firefox to start trusting this site's identification. Even if you trust the site, this error could mean that someone is tampering with your connection. Don't add an exception unless you know there's a good reason why this site doesn't use trusted identification.

Web servers need to send all required intermediate certificates.
The "elearning.louisville-redcross.org" server doesn't send the "Network Solutions Certificate Authority" certificate.
If Firefox hasn't stored that intermediate certificate from a visit in the past to website that has send it then you will get the untrusted error message.
