I've upload my files but it don't work on the Internet. What Am I doing wrong?

The main reason we usually see this case is that the user have uploaded his content to the root of his account and not in the public_html folder.

All files needed to be called from a browser need to be uploaded to public_html.

Their is no other way or folder to make your site to open properly to your visitors then to put your files in the public_html folder
