Any website that is using SHA1 SSL (1024 bit) certificate will need to upgrade SSL certificate to SHA2 (2048 bit encryption)/SHA256 SSL. A website using SHA1 SSL will need to upgrade to SHA2 SSL and all will be okay.
Don’t panic. Contact your developer and he can check or contact your hosting company and they can check. If you are not up to par, your developer can take care of it. It’s not a very expensive fix. Don’t have a developer, contact our Interloper, Inc. and they’ll help you out.
