комп пересоберу перепроверю еще раз все по строчкам везде

Message: Undefined variable: news
Filename: templates/footer.php

Message: Undefined variable: films
Filename: templates/footer.php

В файле templates/footer.php пытаешься вызвать переменные films и news которых не существует. Нужно их создать в контроллере.

Я не знаю, у меня нормально все. Я скачивал исходник из последнего урока:

https://ibb.co/J5PZLky

Смотри где используется templates/footer.php, может у тебя контроллер другой какой-то используется для страниц восстановления пароля.

вот сам файл футера 
        </div>
          <?php $this->load->view('templates/menu', $news, $films); ?>

Смотри какие переменные передаются во view: $news, $films. Ошибка твоя как раз об этом и говорит, что эти переменные не определены у тебя. Для общих, таких как footer или menu, есть MY_Controller (лежит тут \application\core\MY_Controller.php). В этом контроллере и задаются эти переменные для footer:

<?php 

class MY_Controller extends CI_Controller {

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

		$this->data['title'] = "КиноМонстр - сайт о кино";

		$this->load->model('News_model');
		$this->data['news'] = $this->News_model->getNews();

		$this->load->model('Films_model');
		$this->data['films'] = $this->Films_model->getFilmsByRating(10);

		$this->data['category'] = "";
	}
}

Контроллер Auth должен наследоваться от MY_Controller, чтобы были заданы переменные для footer:

class Auth extends MY_Controller

В исходном коде и в видео это все есть.
