Flexslider Gallery Not Loading.

Flexslider Gallery Not Loading.

Hi,

I'm trying to get flexslider working but it doesn't load (On iphone and chrome desktop). It did previously work when I was using a single html file for all pages, but it's now in a single html file with only one page.

If you visit (Link removed) and then click the top selection in the list "Amber Gallery", you may see a thin grey line where the gallery images should be.

It sometimes works if you go straight to the link at:  (Link removed) or refresh the page once there.

Using latest 2.1 flexslider, and 1.9.1.min.js and mobile 1.3.1

Can anyone advise?
Thanks.
