Hi,
I need to disable the add to cart button on this site across all products. I have marked the 'Display 'Add to cart' button' field as 'no' in the Display Configuration but it still shows. Is there somewhere else I need to disable this?
Thanks

It's OK, I've found the problem - it was in the module.
