Checked the issue from our end and we are experiencing it too. Thus, supposingly there’s a Facebook bug going on. Unfortunately we cannot do anything on this at this moment.
We recommend you to contact your local Facebook rep to notify them about this.
If the issue is still up within 3-4 hours from now, we will also inform our global Fb contact on this and cc you on the email.
Anyway, as long as you cannot geo-target please do not publish any content.
