Pinterest button not working

Hi, I just found this plugin tonight and it looks great. But for some reason the Pinterest button doesn’t work; clicking it does nothing. All I see is some javascript in the status bar.

Here’s a page, for example: http://www.emptymirrorbooks.com/beat/review-the-stray-bullet-william-s-burroughs-in-mexico.html

Any suggestions would be welcome. We get quite a number of shares via Pinterest so it’s important to us to get this working.

Thanks!
Denise
