Detailed Description: 
I would like to know how to enable it with my Cloudflare account because when I try to enable it doesn't work.

Additional Information
This is the message that I receive when I try to enable it:
"CloudFlare is already activated for "gigapages.net" under a different account. If you want to enable CloudFlare through this partner, please <a href="https://www.cloudflare.com/dns-settings?z=gigapages.net" target="_blank"> log in to your CloudFlare account and choose "Disconnect" on your CloudFlare DNS Settings page.</a>"
