I am not sure what is going here and any help is appreciated.

I did a new website for a friend, but when you enter her domain name: marquisdiamondstandardpoodles.com, her old Home page appears. You can click on any link in the nav bar and it takes you to the site I designed for her.

Through FileZilla (thanks gwpriester for that suggestion for uploading a website), I deleted all of the old files on the host server (to make sure there weren't any conflicts). Then, I uploaded all of her files, but the old Home page is still the first thing that comes up.

Any suggestions?
