Thanks for the admin details. The issue wasn't with JFBConnect itself, but with a general Joomla configuration issue. To fix, I did the following:
* Went to Users -> Access Levels in the admin area
* Clicked on the "Registered" group
* In there, only "Administrator", "Publisher" and "Super Users" was checked.
* I checked "Registered" and hit save.
Voila! Modules show on the front end. Please verify that setting is what you want and things now work as expected. Also, you should consider deleting the Manager, Author, Editor and Publisher user groups if you don't plan to use them. They're just adding more complexity to your configuration.
I hope that helps, but if you need anything else, just let me know.
Thanks,
Alex
