Sorry for the delay. I'm not sure why the social buttons would cause the modal to shift over. There are the following Javascript errors being thrown on that home page:
Uncaught TypeError: Cannot call method 'getProperty' of undefined (index):1
Uncaught TypeError: Object [object Object] has no method 'slideshow' widgetkit-c4974254.js:15
The first issue, I don't think, is from JFBConnect. The second definitely is not.
It's possible those JS errors are preventing some of our code from working properly, but I'm not sure.
Can you disable the share module on another page so that we can have 2 pages to test on.. one that works, and one that doesn't? That should help us narrow things down.
Thanks,
Alex
