OK that’s great to know. So it won’t work by adding images from existing Media content? I have to create a new gallery and upload directly to this new gallery?
I just tested this and it works – I’m happy to use this workaround and look forward to the update!
Also just deactivated and deleted the theme, then re-installed. Issue is not consistent – sometimes I can create a gallery with 3 or 4 images and it will load, but other times nothing – just hangs on the preloader.
I’ve resized all my images, but no good.
Even demo galleries which have successfully imported fail to load, although all the featured images (even for galleries I create) show up on /gallery/
