Hi,
I'm not sure what's going on.
I can see that on your website, the image tags have additional attributes srcset and data-srcset which are probably added by JCH Optimize, and on your link, the srcset contains the data of an empty image, instead of the URL of the image like on other pages.
But I don't know why.
Maybe it's because these images have been optimized and not others ?

Maybe turning off the "Generate WebP images" setting of the HikaShop configuration might help circumvent the problem ?
The best would be to ask JCH Optimize's support as I don't know how they do this.
