I have prepared related products on my page www.metallzaun.de and it worked fine.
However since a couple of days, when you click a related product it goes up to the picture but i does not change the product. Please check it.
This is very annoying and being honest we already want to resign from using wix. This solution for related products is very unprepared. Sometimes when you click ctr F5 the pictures are not added properly. In general this is really bad.
