When I try to go to my site I get the following Error "The home page cannot be found.".  

Common User Issues

This means that either you do not have a page set to be the home page or you have deleted the last home page in your site. In order to fix this problem then all you will need to do is set any page in your site to be the home page.

Please search the liveSite built-in help documentation for "Home Page" for more information about home pages.
