1. Before you do anything else, please check that Ezoic's copy of your site's DNS records matches those at your host as per the instructions here.
2. The next step is to login to manage your domain. You can login here: http://build.sitesell.com/manage.html. Note that your Username and Password to manage your domain are different from the rest of SiteSell. You can find the details in your SBI! Mail email that you received when you signed up, specifically in the P.P.S. section.
3. Click on the name servers link in the menu as shown here:
4. Enter the custom name servers provided in your Ezoic Dashboard. You can find these under Settings > Connection > Nameservers > View Instructions.
5. Email SiteSell Support. Visit the contact support page at: http://support.sitesell.com/contact-support.html. In your message, ask them to "unlock the domain: yourdomain.com" (replace yourdomain.com with your actual domain). Additionally, include the last 7 digits of the credit card you use for SiteSell and your IP address, which you can find here: http://www.sitesell.com/cgi-bin/proxycheck.pl. Your complete request should look like this (replace with your own information):
6. "Hello, please unlock my domain mydomain.com.
The last 7 digits of my credit card are: 1234567
My IP Address is: 43.23.32.12"
7. Wait for a response from SiteSell. They should get back to you within a day, stating that they have unlocked the domain or requesting more information. If more information is needed, provide it, and they should unlock the domain. PLEASE NOTE that they will state that the SiteSell functionality will not work if you change your name servers -- this is not true -- everything will continue to work once you switch to Ezoic AND you'll get the benefit of Ezoic's optimization and SiteSell's great building platform.
8. Once the domain is unlocked, go back to step 1 and try entering the custom name servers generated for you by Ezoic again.
9. Allow up to 48 hours for all changes to take full effect.
