Internal Server error 500

Hey I'm getting an internal server error 500 after the lines

``` php
include '../inc/github-api/github-api.php';

use Milo\Github;

session_start();

$clientId = 'XXX';
$clientSecret = 'XXXX';

$config = new Github\OAuth\Config($clientId, $clientSecret, ['user']);
```

Any ideas?? Thanks
