If you have placed your website in the public_html directory and it is not yet live or you still see the default Heberjahiz page, you need to check 2 things:
1. You deleted the default file public_html/index.php before publishing your website. This is a page that is automatically published when new accounts are created.
2. You have configured the domain name with the name servers of your hosting plan. You can find this information on your customer area> cPanel.
