Fungsi edit menu management wpu-login

disini ada yang buat wpu login ngikutin web unpas ngga? yg tau tolong bantuin dong gan. awalnya di web ini fungsi edit buat menu managementnya ga dikasih liat di videonya jadi gw tambahin sendiri, fungsi edit menu managementnya cuma buat ubah nama menu nya doang, nama menunya dari "menu" ke "management" bisa diubah tapi pas di klik menu management nya, malah muncul view forbidden, yg dari helper di fungsi logged_in, yang kira2 kenapa ya gan? tolong bantuannya yaa, makasih sebelumnya

controller Menu :

public function index()
  {
    $data['title'] = 'Menu Management';
    $data['user'] = $this->db->get_where('user', ['username' => $this->session->userdata('username')])->row_array();
    $data['menu'] = $this->db->get('user_menu')->result_array();
    $this->form_validation->set_rules('menu', 'Menu', 'required');
    if ($this->form_validation->run() == false) {
      $this->load->view('templates/header', $data);
      $this->load->view('templates/sidebar', $data);
      $this->load->view('templates/topbar', $data);
      $this->load->view('menu/index', $data);
      $this->load->view('templates/footer');
    }else {
      $this->db->insert('user_menu', ['menu' => $this->input->post('menu')]);
      $this->session->set_flashdata('message', '<div class="alert alert-success" role="alert">
      Menu telah ditambahkan</div>');
      redirect('menu');
      }  }

sidebar yg ada querymenu :

<!-- Query Menu -->
<?php
$role_id = $this->session->userdata('role_id');
$queryMenu = "SELECT `user_menu`.`id`, `menu`
FROM `user_menu` JOIN `user_access_menu`
ON `user_menu`.`id` = `user_access_menu`.`menu_id`
WHERE `user_access_menu`.`role_id` = $role_id
ORDER BY `user_access_menu`.`menu_id` ASC
";
$menu = $this->db->query($queryMenu)->result_array();
?>
<!-- LOOPING MENU -->
<?php foreach ($menu as $m): ?>
<div class="sidebar-heading">
<?= $m['menu']; ?>
</div>

fungsi logged_in yg gw curiga disini kesalahannya

function is_logged_in()
  {
    $ci = get_instance();
    if(!$ci->session->userdata('username')){
      redirect('auth');
    }else {
      $role_id = $ci->session->userdata('role_id');
      $menu = $ci->uri->segment(1);
      $queryMenu = $ci->db->get_where('user_menu', ['menu' => $menu])->row_array();
      $menu_id = $queryMenu['id'];
      $userAccess = $ci->db->get_where('user_access_menu', [
        'role_id' => $role_id,
        'menu_id' => $menu_id
      ]);
      if ($userAccess->num_rows() < 1) {
        redirect('auth/blocked');
      }
    }
  }
