Geolocation not showing in item view on public site

I have Geolocation 2.1 running on an installation of Omeka 2.1.3 and items that appear on the Browse Map and have map coordinates, do not display the map at the bottom of the item record in the show view. It just has a box that says "Geolocation" but nothing below it. Initially I was using an older version of the plugin but I just tried upgrading to the newwer one, but nothing's changed.

Here's an item:

Thanks for any advice on fixing it.


Is the item you linked to, 434, public? I'm getting a 404 for it.
