为什么我在CodeIgniter中遇到404错误？

Question

I can't understand why I'm getting 404 errors in CodeIgniter.

My default controller works perfectly:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Home extends CI_Controller {

    public function index()
    {

        $this->load->view('home');

    }

}

But my other controller is not working (I get a 404 when I try to access its URL):

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Add extends CI_Controller {

    public function index()
    {

        $this->load->view('add');


    }
}

Here's some other helpful information:

$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'AUTO';
$config['base_url'] = '';
$route['default_controller'] = "home";
$route['404_override'] = '';

.htaccess :

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

I'm working on localhost and all the other controllers from my other applications are working perfectly. This is the 1st time I have this problem.

If there is no controller class, it should show a 404 not found error. Also try controller file name start with a cap.
