You may find yourself unable to access WHMCS after enabling Cloudflare. WHMCS uses non traditional
ports by default, but Cloudflare support these, along with a few more. Assuming your domain is "example.com",
please try one of the following to access WHMCS:
http://example.com:2086 or https://example.com:2087
If the above doesn't work, find clues in the DNS settings of your Cloudflare account, to guess under whic
record WHMCS is accessed.
The corresponding URL might be:
http://direct.example.com:2086
https://direct.example.com:2087
http://direct.example.com/whmcs
