Payloom : iPhone Problem

Working on an artist’s website - using RW6. Have reduced size of images with TinyPNG and have increased speed of loading I think. But now the Payloom isn’t loading properly when used on an iPhone, image below. Works fine on PC and iPad. Link to page: Printmaking | DEBORAH GRICE

When an image is selected this is what happens:

Incidentally - there’s a general problem with the prices uploading incorrectly also. Should be £40 not £4000

I would be very grateful for any advice,


Any ideas why the price is multiplying?
