Domain not working

Hello, I am writing on behalf of my manager who is having troubles with her websites.

She has two websites:
http://www.table-pr.com and ww.tablepr.com
The first one works perfectly well.
However the second one does not work at all and it is the one we would like to keep out of the two.

At the beginning I was only trying to fix http://www.tablepr.com because it did not work with the www in front of it but it worked when only typing tablepr.com. I deleted some DNS things thinking it would help but now it does not work at all.

She bought the domain names from wordpress or godaddy (she can’t remember) and she also uses google sites to manage it. I think google might be the reason why it is not working but I don’t know I’m really confused.
I am not sure what to do to get it to work. Can someone please help?
Thank you very much.

Have a lovely day/evening,
Pauline
