iPad issue

This now works pretty well in everything I’ve tried but the iPad. After 1-3 clicks in lightbox navigation, or swipes, the same result: the page reloads after an error (undisclosed what error, exactly.)

This only applies to iPads, not iPhone 5 or 6. I tried it on the latest models in the Apple Store, just to be sure it wasn’t a local issue.

Any ideas?

Apparently there are similar problems, just on iPads, but nothing helped me resolve the issue. If the JS were not minified, I could maybe hack a solution.
