The security for the vanware.co.uk
domain no longer uses a conventional SSL certificate. Instead it uses a new feature of cPanel, called AutoSSL. This uses free certificates from an outfit called Let’s Encrypt, which is part of the Linux Foundation. AutoSSL is completely stable, and is the option of choice for most smaller domains. The purpose is not to save money, but to avoid the absolute polaver of replacing the certificates manually. The Certificate Authorities were the problem, not the solution. They were either greedy or incompetent, or both.
