Artfully Plugin Not Working, Javascript Error in Console

I’m trying to get the plugin to work (FA account linked to Artfully). We use the Bridge theme. My event and a donation box/button appear on the page (ticketing is currently turned off) but clicking the Donate button or trying to put tickets in your basket doesn’t do anything (it actually subtracts the tickets from inventory behind the scenes, but nothing else). Here’s the error I get in Chrome and Safari…If you update the plug-in please let me know.

I’m not including the URL of the test page I was working with–if I leave it published it’ll get crawled and I don’t want that. But maybe knowing the error will help for the next version.

Uncaught TypeError: Cannot read property ‘render’ of null
