IMPORTANT: cPanel no longer supports Cloudflare, and because of that, neither does HostPapa. If you wish to enable Cloudflare, please follow the steps in our Knowledge Base article How to enable Cloudflare on your domain.
For security reasons, Cloudflare does not proxy traffic to wildcard subdomains. You have to explicitly list each subdomain as a CNAME in your DNS records to be able to activate Cloudflare.
If you need help with your HostPapa account, please open a support ticket from your dashboard.
