/hsphere/local/home/[site]/[file].php is a file path, not a typical URL. Are you using some sort of CMS or blog software? If so, this looks like it can't find a required php file. Check to make sure you've uploaded all the files to the correct locations, have your app's configuration file edited correctly, and so forth.
If that's not the case, are you sure you have the domain name correct at your registrar? In your HSphere account?
