A possible reason is that your homepage is labeled incorrectly. Please note that the homepage of your site needs to be called one of the following:
index.php
default.php
index.htm
default.htm
index.html
default.html
index.shtml
default.shtml
Please note if your homepage is not labeled one of the names listed above, you will not be able to see your site. Also make sure that you upload all contents that you want visible on the internet to the public_html folder. If you upload your website files to any directory other than "public_html" then your web site will not work.
