shortcode not working anymore…

Hi,

Thanks for this amazing plugin.
I have been using it for sometime.

All of a sudden it doesnot work anymore.

for example, for the lightbox by this page http://h4bs.com/portfolio/ I see the button, but it does not lead to the linked page…

How teo get it working again?

Thanks!
