Hello all,
As an update to this I have deleted all events on this site as I was getting as many as 14 duplicates of the same event when using the hourly Facebook auto import option. As most people seemed to be having problems using the hourly setting I also tried it on twice daily instead. This improved the situation and gave less duplicates but events are still duplicating. For example the same event is entered twice for today.
I hope someone can find a solution because otherwise this is an excellent plugin.
