Why does my website not show in the browser?
Make sure you uploaded the index.html (may also be .php or .htm) file to the main catalog in your FTP. The same applies to any subpage — for example, when you create a link to subpage.html but you forget to upload this file, you will be redirected to a 404 error page. To learn more about the 404 error, please read this article.
If you have an 500 error, please read this article.
