Hello, This addon is not working currently due Facebook API changes. Facebook has restricted access of Permission in API from 4th April due to recent Privacy issue. They have new policy & rules to get Post data and restricted events data over API, So You are not able to import post from Facebook for now. Facebook is making changes in their Platform and they will fix these issues soon. Best regards,
We are still waiting for updates from facebook group to xenforo hopefully. P.S. We have just bought facebook group to xenforo 2 not yet used.
I too just purchased this today and realised it doesn't work ! Looks like I may need to request a refund until the issues are fixed.
