PhotoSwipe doesn’t work

Hi,

I have bought metaslider pro, installed it, also installed MetaSlider Lightbox, then
Responsive Lightbox & Gallery. Finally I bought Responsive Lightbox – PhotoSwipe and installed it. I have chosen PhotoSwipe in the setting of Responsive Lightbox & Gallery. I have typed in my licence number an have listed 2 sites on your page for the licence (which is for 5 sites).

Unfortunately the lightbox is not working. both websites use DIVI Template. example:

all other lightboxes on both websites work well, all but photoswipe.

What can I do to make it work?

Regards
Christian
