I have my exhibits with images as Visual Index. I have the "on click" set to overlay. They were working perfectly earlier today; when I clicked on a thumbnail the larger version would show up with all the overlay controls (arrows and an "x"). Now I just looked and this is not happening. When I click on a thumbnail the larger image just opens as if you were right clicking on the image to open it in a new tab/window (but it's staying in the same window). None of the controls are showing up.
I've been customizing the code for appearance but I never touched anything that would have been related to the Visual Index pages (that I know of).
Please help!
