Your home page likely has component output disabled, which is an option in many templates. The current release of the SCLogin module requires component output to be displayed on the page for the modal to work. The next release (due out next week) uses a different system that does not have the same limitations.
I hope that explains. The problem will be fixed soon though, and I apologize for the inconvenience,
Alex
The new release of JFBConnect has been released, along with the new SCLogin module. Please update and let us know how it goes or any issues you run into.
We'll be updating the Open Graph documentation and uploading videos over the next 2 days. The documentation right now is a bit stale, just so you know. If you get confused, or run into issues, it's likely not you.. it's us.
Just want to warn you.. of course, if you do have problems, just let us know!
