Hi there @kenwestphal, thanks so much for all your comments on this thread. I've tried everything multiple times, including your blog but I can't seem to get it to work for me. When I click the button it takes me to the top of the page, but no lightbox appears. I've updated the header code for featherlight/1.7.2, and added the jquery to the header. Has anyone else encountered similar problems or have any suggestions? I would be so grateful for any suggestions!
