The error logs are full of this:

Caused by (sample below) introduced in cac2032 (cc @jblas):

$category_data = array(

        name => "Animals",
        description => "All your favorites from aardvarks to zebras.",

This isn't javascript, no unquoted keys here! Unforunately, not unlike javascript, PHP is famous for not letting failures show very visibly.

In this case it will actually try to access a global constant named animals (conventions usually recommend constants be written in CAPS). And if it can't find that constant, it will use its name as a string value and continue on (Yes this means in PHP, array keys can be created from expressions).

Just quote them, and don't forget to develop locally with error_reporting -1 (all errors), and keep an eye on /var/log/apache2/error_log (or your local equivalent).
