Lightbox 2.8.2 noy working on Seasons theme

After following all the steps to implement Lightbox, when i click on images thumbnails i got the original image opened, not the lightbox.

Please take a look here http://beminuscula.com/omeka/items/show/2

My browser inspector (safari) indicates that lightbox.min.cs and lightbox.css are loaded.

Could you help me please?

First, just to double-check, could you link to the instructions you followed? I've seen a couple different patterns.

I am having the same issue. I followed these steps: https://omeka.org/codex/Adding_LightBox_to_Omeka
