Gallery not responsive on ipad for highend theme

My galleries do not work on the ipad. When I click on the gallery image, it just opens up a page with that first image. It does not scroll nor does it have the icons at the bottom of the page.It works fin on my computer. Please help asap. Thanks!

To check it, view on ipad, then click any of the galleries. You will see that the only image is the featured image.
