In the latest upgrade of SocialEngine that has been released (v4.1.6), SE has made some changes in the in-built Facebook integration. Our 3 Facebook related plugins: "Advanced Facebook Integration / Likes, Social Plugins and Open Graph", "Facebook News Feed, Friends, Invite and more" and "Facebook Feed Stories Publisher" are curently not compatible with this upgrade. Thus, if you have these plugins, and are upgrading your site to SE 4.1.6, then you should first disable these plugins.

We're working hard on making these plugins compatible with SE 4.1.6 and will soon release their upgrades.
