“The name of the security certificate is invalid or does not match the name of the site”
Customer Support >SSL Certificates > FAQ

This error will occur when the certificate is being used on a different fully qualified domain name than to which it has been issued. For example if your certificate is issued to www.domain.com then using it on secure.domain.com will result in a name mismatch error.
you may also see this Security Alert if you have not installed the intermediate certificate and rebooted your server.
