When I use HTML in the caption of the very first image, it makes duplicate captions (seems to be loading ALL the captions that I’ve added so far) appear when you click on each following image in the gallery. It’s very curious.
Tried this: I took the HTML tags out of the first caption and then others with markup work properly. But I want them to be the same. Wah.
Tried this: Changed lead image. No go. It’s not specific to a particular image, just the first one every time.
