Question: PHP or ASP pages do not open on a website hosted in Plesk: HTTP Error 404.3 - Not Found


Applicable to:

• Plesk for Windows

Symptoms

When loading a .php / .asp page in a web browser, it fails to load with on of the following error messages:

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration.
If the page is a script, add a handler.
If the file should be downloaded, add a MIME map.

Most likely causes:
It is possible that a handler mapping is missing. By default, the static file handler processes all content.
The feature you are trying to use may not be installed.
The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
If ASP.NET is not installed.

Cause

Handler mapping for PHP / ASP is not configured.
