Hi Mary,
Are you using an Access Token from your own Facebook app? In order to display events you’d need to use a Page Access Token from your own Facebook app by following these directions. It’s not possible to use a Page Token retrieved through our plugin, or anywhere else, to display events right now. Facebook hasn’t reopened access to public events yet and so the only way to display them is by using an Access Token from your own Facebook app which will then allow you to display events from a Facebook page which you manage.
You can use the token from our plugin to display any other post type – just not events. So you could retrieve a token from your own Facebook app and then add it into your events shortcode like so: [custom-facebook-feed type=events accesstoken=YOUR_OWN_TOKEN]
Let me know whether that makes sense, or if you have any further questions at all, and apologies for any confusion.
John
