Okay cool, I'd already done that and and everything is looking good. I'm by no means a DNS expert. Was concerned there may be clashing records once I updated the details at my registrar. Thanks for the help.
My account is seeing the Apache is functioning normally issue. I previously had a Prime account.
I would like to remove my DNS records from X10, and use my domain provider instead.
Ps - I've been using x10 for 10+ years and have been grateful for the service, especially when I was a student.
