still having the same issue for 2 weeks now:
Could not determine the nameserver IP addresses for “antoniojennings.com”. Please make sure that the domain is registered with a valid domain registrar.
Dead-i said ya'll were looking into it. what is going on
definitely an issue with x10. signed up with byethost. changed the nameservers on godaddy to point to them, within a few mins my domain was parked and connected to my site
Sorry for the delay. This is still an issue on xo3, and we're working on resolving it. In the meantime, I'm happy to park the domain on your account for you, if you still need it.
i also have same problem i tried both the themes. cannot work it out.
