Interesting, I would appreciate details how to set this up should you get automatic slideshow working again. I’m using the image array or look-up/split to get manual slideshows.
I don’t know who runs that glidetools.ml website, but I have a feeling it’s ran by some random user and not Glide. Maybe whoever runs it isn’t maintaining the website, so some recent updates stopped it from working. I think all it did was import the CSS that was needed for the slideshow to work. I thought I saw the actual underlying CSS somewhere in the forum, but I haven’t been able to find it yet.
