Hello,
Dear Olga
I attach links to the screenshots where the screenshot with the name three does not show any image from the product gallery. The product only has 2 images but when applying the arrows to see the other images, a view called 2/3 appears in the container that does not contain anything at all. This situation occurs in all products, if the product has more images, a view without image (without content) will always appear, which is annoying for the customer.
I hope I have been a little more explicit thanking you in advance for your help.
