I installed this plugin to check out it's custom post type functionality and it simply exploded everywhere.
I was running with DEBUG turned on but this plugin through SO many errors I turned it off. Then it continued to complain about missing files etc.
Primarily, as an example of custom post types, it could be good, but WordPress is complaining of deprecated features since 2.0 - which is really old now.
I tried this both locally and on my HostGator server. It just throws errors about missing files.
