FACEBOOK Counter at "0"

For my test it is possible to see this right with the ID:
http://graph.facebook.com/1382010798698729

Maybe your problem server to connect with Facebook.

In the plugin settings you can generate a test report with connections, please generate the report and show me using it here pastebin.com

Here the error:

    [body] => {"error":{"message":"(#4) Application request limit reached","type":"OAuthException","code":4}}
    [response] => Array
        (
            [code] => 403
            [message] => Forbidden
        )

Looks like you did a lot of testing the saving plugin settings for a day.
This made the plugin tried to communicate with the Facebook API and made it reach the daily limit.

Just wait 24 hours it will take to get the data back and so the Facebook count will appear 🙂
