Routes in Codeigniter - 404 Page Not Found

Question

Can someone tell me, where the issue is ??

This is my controller

class Support extends CI_Controller {
    public function __construct()
    {
               


        

Answer 1

Since the above answer did not work for me, I just added this function in my default_controller, and it worked.

    public function __construct() {
    parent::__construct();
    $this->load->helper('url');
    }
