404.3 Error for .php extensions on IIS 10

Question

I've used WEBPI to install PHP 7.1 on IIS 10 in an attempt to develop PHP on a local machine. I get this error when navigating to a .php file:

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.

• CGI is activated

• ASP.NET is installed

• The handler is mapped in FASTCGI (C:\\Program Files\\PHP\\v7.1\\php-cgi.exe) in the IIS Manager

• HTTP Activation is ON

• aspnet_regiis.exe -ir has been run

Why aren't PHP file extensions being recognized?

Answer 1

Have you checked your handler mappings? It should contain a mapper of FastCGI to php files. Fixed the error in my case.
