So I was randomly puttering around on varoper.com and made the scandalous discovery that, in the art section, none of the images were opening in lightboxes. For shame! First came denial: I went through a brief period of self-doubt where I began questioning whether the lightboxes had ever really worked in the first place. The came the bug-checking. And then came the googling. Apparently Fancybox (the particular brand of lightbox that I’m using) doesn’t work with the latest version of jQuery (version 1.9.0). This thread gave me some options as to how to fix it, and I went with adding the migration script below my jquery script. And, fixed! Woo.
