You can change your primary domain via the ‘domain’ section of your control panel. Just click on the link that says ‘Click here to change your Primary Domain’.
Warning: When changing your primary domain name, you will lose all existing email accounts and subdomains. You will need to recreate all subdomains and email accounts on your new domain.
If you still want your current domain to work, you can “park” it via the domain section of your control panel. Just click on the link that says ‘Add a parked domain’.
Please remember your_username.phpwebhosting.com will always work. There is no need to park this domain.
Note: If you get the message “That is not a valid domain or the domain is already in use” when trying to change your primary domain, this most likely means the domain is already parked on your account. In order to make a domain your primary domain, you must first remove it as a parked domain. You can remove parked domains by clicking on the ‘List Parked Domains’ link then clicking ‘delete’ next to the domain you wish to remove.
