        $this->_locales = Configure::read('I18n.locales');

It seems like \Cake\Core\Configure::read('I18n.locales') of type * is incompatible with the declared type array of property $_locales.

        $this->_locale = I18n::locale();

        $this->_cookie->configKey('language', [
            'expires' => '+1 year',
            'httpOnly' => true
        ]);

The expression $this->_session->read('Auth.User.language') of type string|null is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

                //If the user has not the cookie, we set the cookie.
                if (!$this->_cookie->check('language') || $this->_cookie->read('language') != $this->_session->read('Auth.User.language')) {
                    $this->_cookie->write('language', $this->_session->read('Auth.User.language'));
                }

                $this->_locale = $this->_cookie->read('language');
            }
        }

        //The user want to change his language.
        if (!is_null($this->_controller->request->getParam('lang')) && isset($this->_locales[$this->_controller->request->getParam('lang')])) {

                    ->where(['id' => $this->_session->read('Auth.User.id')])
                    ->first();

                $user->language = $this->_controller->request->getParam('lang');
                $this->_controller->Users->save($user);
                $this->_session->write('Auth.User.language', $this->_controller->request->getParam('lang'));
