Not working with Twenty Seventeen theme and WordPress 4.7?

Hi.

I can’t make the plugin work at all on the frontpage of the Twenty Seventeen theme. It does work on a page, though…
The front page pulls in pages to display on top of each other in a vertical scroll. When looking at the page on its own, the lightbox works fine. When looking on the same page but as part of the front page, it doesn’t. The image just links to the image file.
I tried deactivating all other plugins, same result. I tried using the footer as loading place-option, same result.
Any tips appreciated, thanks.

Best regards,
Asser.
