Hi @007me,
Sorry for the late reply.
Please update the plugin to the latest version 1.7.4 and reconnect your FB connection in each collection:
1. Go to the integration of your admin FB profile https://web.facebook.com/settings?tab=business_tools&ref=settings
2. Delete the Widgetpack application
3. Go to your wp-admin
4. Delete all connected FB widgets and shortcodes
5. Create new widget and shortcodes and connect your FB page(s) again.
Sorry, we must changed the API permissions in the Facebook API and this steps are mandatory to fix the issue.
Let me know how it goes.
Thanks!
