Usually, your files not showing up can be a general human error. First, does your site work? If it does not be sure to talk to a support representative via Live Chat or Support Ticket. If your site works the usual problem is that you did not put your files in public_html. You should put your files in either www or public_html as they go to the same place. The folders are linked to be the same thing. If your files still don't show up the best thing to do would be to try re-uploading them. If nothing works, open a support ticket and we'll be glad to assist you.
Thank you for your interest!
