Mines doing the same thing; It looks very similar to the lightbox issue woo commerce had after the recent upgrade; I did the fix for woo commerce itself and that fixed the main product pages, but the quick view modals are still opening the file directly; I’d bet anything its the same issue, just not sure how to fix it as the coding for the plugin has less documentation and I’m not that familiar with it; I’m hoping my comment will help your post gain some attention so we can both get it fixed.
