You appear to be on some kind of partner setup, you are using your host’s DNS, not Cloudflare’s. If you need help with your setup, I would recommend you contact your host.
yes i am using Siteground hosting and they setup it. and asked me to go to Cloudflare support when i discussed the matter.
Actually i have set NON-WWW version as my website’s main version in Google search console and same rule i have defined in my htaccess file as if website is accessed with WWW version then redirect to NON-WWW version. And their support staff said that the NON-WWW version is not allowed in Cloudflare? now i am too much confused in these www/nonwww version
