It looks like you're trying to use the Social Streams feature, but something isn't configured correctly. Have you followed the
Social Stream configuration guide
?
Also, while the Social Streams feature is very useful and recommended, it takes a little more work to get going. I'd also recommend trying the Facebook Page Plugin, which can show you the stream from your Facebook Page if that's all you want. You can see what it looks like below:
developers.facebook.com/docs/plugins/page-plugin
To configure it with JFBConnect, you need to instantiate the SCSocialWidget module and hopefully it's smooth sailing from there.
Thanks,
Alex
