No - I am getting the same thing. I hope it is because it takes time for the DNS to update.
Unless, of course they have changed the name servers and they are no longer
The instructions on the new cpanel are not very clear - and I am getting too tired to fight any more.
Perhaps instructions to back up the files should remain as is.
Then instead of all the migrate stuff - simply tell everyone to delete their accounts, and give everyone a link to create a new account on the new server (instead of being sent to to the old server time and time again).
Then explain how make a new account and upload your website.
And then tell everyone we may have to wait 24 hours for the DNS to update.
The new cpanel might be pretty but it is very confusing - the old cpanel was user friendly far easier to use in my opinion.
