Trouble getting the tutorial working. (Apache)

I'm trying to get the tutorial working.

I'm getting an PhalconException: IndexController handler class cannot be loaded message

I have an alias set up as Alias /tutorial /opt/tutorial/public

When i accesst the page https://172.25.12.11/tutorial/ I get the error message.

mod rewrite is on. i have also tryed this in the main web dir with no change.

My file structure is

/opt/tutorial/
|-- .htaccess
|-- app
|   \-- controlers
|       \-- indexController.php -- (I have done upper and lower case i no change)
|   |-- models
|   \-- views
\-- public
    |-- .htaccess
    |-- css
    |-- img
    |-- index.php
    \-- js

indexController.php file

<?php

class IndexController extends \Phalcon\Mvc\Controller
{

    public function indexAction()
    {
        echo "<h1>Hello!</h1>";
    }

}

index.php

<?php

try {
echo('1<br>');
    //Register an autoloader
    $loader = new \Phalcon\Loader();
    $loader->registerDirs(array(
        '../app/controllers/',
        '../app/models/'
    ))->register();
echo('2<br>');
    //Create a DI
    $di = new Phalcon\DI\FactoryDefault();
echo('3<br>');
    //Setup the view component
    $di->set('view', function(){
        $view = new \Phalcon\Mvc\View();
        $view->setViewsDir('../app/views/');
        return $view;
    });
echo('4<br>');
    //Setup a base URI so that all generated URIs include the "tutorial" folder
    $di->set('url', function(){
        $url = new \Phalcon\Mvc\Url();
        $url->setBaseUri('/tutorial/');
        return $url;
    });
echo('5<br>');
    //Handle the request
    $application = new \Phalcon\Mvc\Application($di);
echo('6<br>');
    echo $application->handle()->getContent();
echo('7<br>');
} catch(\Phalcon\Exception $e) {
     echo "PhalconException: ", $e->getMessage();
}
