CodeIgniter 404 Page Not Found, but why?

Question

I am using CodeIgniter for two applications (a public and an admin app). The important elements of the document structure are:

/admin
/admin/.htaccess
/admin         


        

Answer 1

The cause of the problem was that the server was running PHP using FastCGI.

After changing the config.php to

$config['uri_protocol'] = "REQUEST_URI";

everything worked.
