Robert,
I just went to your home page, clicked the SCLogin Login button at the bottom and then clicked the "Register" button in the modal popup. I was brought to the following page:
vertex.eyecandyvi.com/index.php/componen...s/?view=registration
In there, I'm correctly seeing the Register With <Facebook> section at the top.
Are you still not seeing it? Let me know, but it seems like everything's going correctly now.
Thanks,
Alex
