[Plugin: Instapress] Fancybox effect not working

Thanks for the great plugin. My installation of instapress is not working with fancybox. Choosing the fancybox effect results in instagram thumbnails that do nothing when clicked. Choosing no effect works fine and clicking the thumbnails resolves to the instagram page for the image.

My theme also makes use of the fancybox effect, is there some kind of conflict? If so, is it resolvable?

Thanks in advance.
