I have just installed the latest build (3.93) on dnn v 5.5.1, and when I set the lightbox to be active, it doesn't work. I have installed all the lightbox files correctly (I use lightbox extensively in a custom built xmod gallery on a lot of other sites), but when I click on the thumbnail to open the larger image, the image just opens up in a new window - as if the lightbox script is not getting set / triggered correctly. This is the error as generated by IE:
