Moving url

Hi guys,

So I’m having trouble with a site. I have a site with the domain Mae therunwaygirl.com
However, the owner of the site wanted to change from WordPress to blogger. Currently She is using 1and1 as her server.

What she did was went to therunwaygirl.com/wp-admin and went to settings and deleted her domain from the admin page.. Now she can no longer access her admin page.

So with that being said, she still wants to move her domain name to blogger.

Any tips how or what she should do? Should she just remove the her website from that domain name in 1and1 and then proceed to create a new website under that domain with blogger?

Please let me know!

Thank you so much
