Unable to move SLIM3 Install from 5.7 box to 7.2.3 box

So we moved a slim 3 from a 5.7 box to 7.2.3 both on apache

Question 1 is HOW can I turn on logging to see what is going on? I haven’ not been able to do this.

Question 2. The function below to create the view container is failing

So the container in our APP PHP which is failing is

$container['view'] = function ($container) {
    $view = new \Slim\Views\Twig(__DIR__ . '/../resources/views/', [
        'cache' => false

    echo "<br><h1>Wontttttt Load Twig View container</h1>";


    $view->addExtension(new \Slim\Views\TwigExtension(

    $view->getEnvironment()->addGlobal('auth', [
        'check' => $container->auth->check(),
        'user' => $container->auth->user()

    $view->getEnvironment()->addGlobal('status', getenv('STATUS'));

    $filter = new Twig_SimpleFilter('unserialize', function ($string) {
        return unserialize($string);

    $filter = new Twig_SimpleFilter('url_decode', function ($string) {
        return urldecode($string);

    $view->getEnvironment()->addGlobal('flash', $container->flash);

    return $view;
