Every sub-domain I add results in the www entry also being added. But I don't want to use the www version, and so I am not adding the relevant DNS A record, which results in cPanel/WHM complaining the sub-domain is not secure because the www counterpart has no certificate because it does not resolve to any IP addresses on the Internet.
How can I stop cPanel/WHM adding the www for sub-domains?
