Hi Phill and thanks for your answer. I have hitted the clear buttons in the settings of FooGallery with no success; the problem is still here.
I don’t think it’s a cache issue. I have visited https://emilcar.fm/tienda/ in Chrome, Firefox and Safari, with public and private sessions. When I reloaded the web page some hidden images showed up, but then, others disappeared. And so on.
I never get to see all the images in all the galleries, so I think it’s not a cache issue.
