It is possible you have reached this page because:
The owner has yet to upload their website.
This is the default page for new websites. You need to upload your own files to the server and refresh this page. Upload your files to public_html via FTP or the File Manager.
The default index.html file still exists.
As well as uploading your own files, you need to make sure the default index.html file has been removed. If your site uses a different suffix, such as index.php, then the default index.html file is still in the public_html folder and needs to be deleted.
