There are a few errors in the console, but I don't think they are relevant (How do I post images in the comments i.e. upload an image?) It all looks fine in the preview, and even if I look at it in the comments list (https://www.chessvariants.com/index/listcomments.php?order=DESC) all looks fine, it's just on the Interactive Diagram page. Other peoples diagrams look fine as well, except for the large gap at the top of the diagrams using betzaNew.js, but I assume that's normal (seems related to the aspect ratio calculation, perhaps it doesn't play well with the iPad Safari)
