Site certification error

I was testing my site after upgrading to 4.5.2 and I found an issue with my account page on it. It sends me an Insecure connection warning in Firefox and will not allow me to access the page. It says that I have improperly configured my site. Prior to upgrading I had no issue. How do I correct this issue I am a budding coder so hopefully it is an easy fix.

This is the message I receive from firefox:

simplykinkdesigns.com uses an invalid security certificate. The certificate is only valid for the following names: *.prod.phx3.secureserver.net, prod.phx3.secureserver.net Error code: SSL_ERROR_BAD_CERT_DOMAIN
