Why You Should Not Install mod_cloudflare
If you use CloudFlare, you should not install mod_cloudflare. In fact, there's nothing you need to install or configure on your server.
ServerPilot configures your server by default to understand the X-Forwarded-For headers used by CloudFlare. Your log files and your PHP scripts will use the real client IP addresses, not the CloudFlare proxy server addresses.
If you attempt to install mod_cloudflare, you may break your server.
