If you haven't already, please make sure you're going through the
Open Graph Actions
documentation.
If nothing is being triggered, below are the best debugging steps I'd suggest:
1) In the Configuration area of JFBC, set "Enable Debugging Mode" to "Yes". That may show a 'blue box' in the bottom right when the action should be triggering with information as to what's gone wrong.
2) Enable the "Include jQuery / Bootstrap" setting in the JFBConnect configuration area. There are lots of templates and extensions that include jQuery and/or Bootstrap, but different configurations can conflict. Our version is a special namespaced version just for JFBConnect which won't conflict with other extensions and is sure to work with ours.
3) Check the Open Graph -> Activity Log in JFBConnect for any errors that area appearing there. If you see any, let us know what they are, as that will help narrow things down.
I hope that helps get you started, but if not, let us know, and we'll help however we can.
Thanks,
Alex
