Как исправить ошибку при использовании HybridAuth в Codeigniter: Endpoint: Error while trying to init Hybrid_Auth: You cannot access this page direct?

Ошибка возникает тут:

protected function authInit() {
		if (!$this->initDone) {
			$this->initDone = true;

			// Init Hybrid_Auth
			try {
				if (!class_exists("Hybrid_Storage", false)) {
					require_once realpath(dirname(__FILE__)) . "/Storage.php";
				}
				if (!class_exists("Hybrid_Exception", false)) {
					require_once realpath(dirname(__FILE__)) . "/Exception.php";
				}
				if (!class_exists("Hybrid_Logger", false)) {
					require_once realpath(dirname(__FILE__)) . "/Logger.php";
				}

				$storage = new Hybrid_Storage();

				// Check if Hybrid_Auth session already exist
				if (!$storage->config("CONFIG")) {
					throw new Hybrid_Exception("You cannot access this page directly.");
				}

				Hybrid_Auth::initialize($storage->config("CONFIG"));
			} catch (Exception $e) {
				Hybrid_Logger::error("Endpoint: Error while trying to init Hybrid_Auth: " . $e->getMessage());
				throw new Hybrid_Exception( "Endpoint: Error while trying to init Hybrid_Auth: " . $e->getMessage(), $e->getCode(), $e );
			}
		}
	}

Не могу понять почему. Почему он не может инициализировать?
