FB Connect button appears, but does not work.

Hey guys,

I've added the FB Connect Login button to my theme header using a few different methods, but each just gets the button to show - nothing happens when you click the button. I'm using BuddyPress.

1. The first method I used to input the shortcode into my theme was:

<?php echo do_shortcode('[wdfb_connect]'); ?>

- the button showed, but no action.

2. Then I tried a method described recently here by @VeBailovity:

Same result. Button shows, but nothing happens when you click it.

You can see it here, using the second method above:
