Hi Catherine,
You’re not missing anything at all — we actually do not have a back-end demo of Facebook Events. Instead, we offer a full refund on all products within 30 days of purchase. We have found that testing the plugins in your own site environment is the best way to get a sense of how the plugin works and whether it will work to fit your needs. If something doesn’t work out, let us know here in support and we’d be happy to take it back, should it not work for you for any reason.
Does this help answer your question? Please let me know. 🙂
Cheers,
Geoff
