I transferred my domain name out of godaddy to another registrar which i bought with a basic WordPress hosting plan. After the transfer, the site could not load, its says "Domain's server DNS address not found.
Please how can i resolve this?
You should RESET your NS and DNS Records and wait for 24 - 48 hrs and I suggest contact your new provider to help you with DNS Records.
You're trying to tell that even after transfer the domain is still with Godaddy ! I think you should once ask Godaddy Support and which is the domain ?
You must cross-check all your DNS Records as well as the NS Records. Login to your CPanel and search for DNS and check the values at your domain. Also for your ref here's the DNS Lookup Tool which will help you.
