Yet it didn’t helped me a bit. Still all the images are gone.
Would you please check the website for me since it gets really frustrating, I don’t know where to look.
Do images appear on the parent theme? If they do, It means all the code is harmful. Delete all the custom (save it on your PC) and check if the images appear on the child theme, you can delete and install the child theme and add your custom snippet by snippet checking the issue to detect the harmful one.
Yes, I deleted everything in functions.php for the child theme yet don’t see only main image for the product, yet images show fine when viewed in a catalog / slider and other places.
Please refer for the screenshots located in the private content.
