slide skipping

I’ve just noticed slides are skipping on this live site: http://wethink.ws/paspaley-pearls/ (it’s happening on other pages too)

I happen to have the production site still up and it had an older version of wordpress that hadn’t auto updated, and that one still works fine.

Just wondering if you have any suggestions on things I could try.

Thanks for your help,

Belinda
