Resellers can change temporary CP alias to your own Reseller CP URL:

Info – > Admin Settings and change Reseller CP URL

• Set the protocol: http for regular or https for SSL secured
• Enter the new domain name with cp at the beginning. (e.g.: cp.cpwebhosting.com).
• Leave the the port number as is – it must be the same as that of the parent hosting company.

Click  Change.
