I had this and it was because I was still on 3.5.7 not >=3.6
Just found this too, thanks for the quick response Andrei and good luck!
Sorry I can’t send a link as its localhost.
It’s just a table at the moment, here’s a pic.
The add to cart button is the plus.
Ideally I’d like to save them up and post them all in one go (see my other post), but visual feedback will do, as per this image. I just want some sort of indication that someone has clicked the button, without looking back to the cart.
Thanks 🙂
