Where has your https gone?

I don't think it's because of the free certificate. The error description is SSL_ERROR_BAD_CERT_DOMAIN requested domain name does not match the server's certificate. For me it's not a problem to allow exception, but for new users this could be a problem.

EDIT: Just to add that I'm able to open the forum with Chrome on my mobile and also with Opera on PC with warning that some insecure content has been blocked.
