Have you turned on debugging in your config.php? What is the error?

One idea is that you can’t just use the string syntax “sortBy” like above, try putting it on a different line or put the new Pages thingy in parenthesis before adding sortBy().

```php
$posts = new Pages(array($posts_a, $posts_b)); 
$posts = $posts->sortBy('date', 'desc');

```
