In this case, the address listed in the certificate does not match the address of the website your browser tried to go to.
This is what google is telling me. I cut and pasted part of the response below:
One possible reason for this is that your communications are being intercepted by an attacker who is presenting a certificate for a different website, which would cause a mismatch. Another possible reason is that the server is set up to return the same certificate for multiple websites, including the one you are attempting to visit, even though that certificate is not valid for all of those websites. Google Chrome can say for sure that you reached *.worldsecuresystems.com, but cannot verify that that is the same site aswww.alechadesigns.com which you intended to reach. If you proceed, Chrome will not check for any further name mismatches.
