Why has my page or website disappeared?
When you create your site, by default the main index.php page should be stored in the top level (some sites store the index page in a "Home" section.)
If your index page (or any of your pages) are moved or deleted there are several possible scenarios.
A "404 Error" page.
"Forbidden You don't have permission to access /site/sitename/yoursitename/ on this server."
Contact the Web Editor to determine what the problem is.
