Events are not shown

Hi, I have a problem with the plugin when it has to show shared events from a facebook-page. Unfortunately, that doesn’t work.

It concernes the following website:
http://www.berg-oberpinzgau.at/berg-auf-facebook/

and the following facebook-page:
https://www.facebook.com/berg.oberpinzgau?ref=ts&fref=ts

The post (shared event) which is not displayed is the “LeRoXas Veranstaltung”.

Thanks for your help
Regards
