Do you own the domain name you wish to add as a parked domain? If so this is how it has to be done.
1. Go to your parked domains and add the domain favorart.com
2. Go to the domain name registrar where you got the domain and add these name servers .
ns1.x10hosting.com
ns2.x10hosting.com
It will take up to 72 hours for your DNS to update. Depending on your ISP.
