On August 6 2016 Facebook has shut down their API v2.0. For AMPZ the consequence is that retrieving share counts no longer works. Since version 2.1.3 this issue has been fixed and Facebook share counts are again retrieved. In most cases the only thing to do is update to version 2.1.3 (or higher) and clear cache after updating. However, in some cases this does not work. Mostly these are websites with high traffic. This blog post describes what to do if Facebook share counts are not displayed and you are using version 2.1.3+.
