Check your website files.  The page that you want to display first when your web address is typed in must be named index.html or index.htm.  Make sure the filename is all lowercase.  The server is set to default to these options.  

Pages other than the first page can be named as you wish, but we recommend sticking to lowercase and using no spaces or special characters other than the underscore ( _ ) character.  Establishing this habit now makes it easier when it comes time to link pages or pictures.
