Hello Micael Silveira
We have checked and you buy extension on 2015 with standard subscription 12$ and now your subscription is expires and we have updated extension to new version, In new version we use Facebook sdk 5.4 and graph api 2.10. So you need renew extension. You can buy again here:
joomcore.com/commercial-extensions/compo.../jo-k2-auto-facebook . After you buy you can download new version and install upgrade in your site and we will help you check and fixed the problem
Problem because Facebook have updated to new permission
Best regards
Bach Pham
