title: Magento - No items showing on Order View page in admin backend
body: <p>For some reason, items ordered are no longer being rendered on the Order View page in the backend.</p>

  <p>But they are rendered on the Shipping details page:</p>

  <p>I have cleared the cache fully.</p>
  
  <p>Viewing the source, there is nothing rendered underneath the grey heading bar "Items Ordered".</p>
  
  <p>Any ideas folks?</p>
