Are you working with controllers inside a sub-folder? If so, extend the Exceptions class by creating application/core/MY_Exceptions.php

Put the following code:

class MY_Exceptions extends CI_Exceptions 
{

    public function __construct()
    {
        parent::__construct();
    }

    /**
     * 404 Page Not Found Handler
     *
     * @access  private
     * @param   string
     * @return  string
     */
    public function show_404($page = '', $log_error = TRUE)
    {

        /**
         * Quick fix for 404 Override bug.
         * 
         * index.php/non-existent-controller                        -----> override ok
         * index.php/existent-controller/non-existent-method        -----> override not ok
         * index.php/existent-folder/non-existent-controller        -----> override not ok
         */

        $router =& load_class('Router', 'core');
        if ( ! empty($router->routes['404_override']))
        {
            if ($log_error) log_message('error', '404 Page Not Found --> '. $page);

            $config =& load_class('Config', 'core');
            header('Location: '. $config->site_url($router->routes['404_override']));
            exit;
        }

        /* End of fix */

        $heading = "404 Page Not Found";
        $message = "The page you requested was not found.";

        // By default we log this, but allow a dev to skip it
        if ($log_error)
        {
            log_message('error', '404 Page Not Found --> '.$page);
        }

        echo $this->show_error($heading, $message, 'error_404', 404);
        exit;
    }
}
