Greetings! I recently created a subdomain and i want to it to be cached and protected by cloudflare.

I tried doing this on the cpanel by clicking on Want to run on CloudFlare? link but i received this message "A type records cannot be directly routed though the CloudFlare network."

Kindly guide me how to change it to a cname instead as I am not familiar with these things.

Also regarding my subdomain i want all www.subdomain.domain.com to redirect to http://subdomain.domain.com
How do i do this? Thank you
