[UPDATE 14. August 2018: The DPCalendar FB plugin is working again since version 7.0.4 as we upgraded to the new platform API 3.1. There is still an issue with pages where you are not an admin or developer of. But it looks like a problem on the FB platform as mentioned in this ticket.]
Since the Cambridge Analytica leak, the Facebook developer team takes some measures that this can't happen again. One of the tasks is to review their app platform. A consequence is that apps do stop working and API access is not possible anymore. The DPCalendar plugin relies on the API as it is the official way to access the event data from your Facebook pages. Here is a link to the restrictions they do put in place.
As Facebook is also putting some restrictions for events fetching, it can happen that your DPCalendar plugin is not pulling the events anymore into Joomla. This happened to one of your app too while another one is still working. The problem is that we can't do anything on that part as the API is fully managed by Facebook. We can just wait till an official statement comes out what the proper steps would be to make your Facebook app and the API work again. When you log in on https://developers.facebook.com, you will see an announcement that they are not reviewing any app at the moment. But for the events API your app must be reviewed as stated here when you want to go public with it. At the moment we are not sure if the apps will still work in development mode as they did before the leak. You can find here more information about the different steps in the life cycle of a Facebook app.
What you can do in the meantime, except to wait? You can create new events in DPCalendar itself or move to another system like iCloud or Google calendar.
