Other Information

Hello, i want to transfer my own custom domain to infinity free but i keep on receiving the error above. I first made sure the DNS servers in my registrar are the correct infinity free name servers. If possible, could you kindly delete the website from the said ezyro server so that i can transfer my domain to infinity free. Thank you..
