I'm really at a loss. I have a web developer who basically 'does things we ask' then leaves us to our own devices, if something breaks, he won't fix it pretty much. 

We asked him to install an extension so we comply with EU cookie law and since then, our add to cart button is not working. Hes uninstalled the extension but still no luck. 

If we use the 'quick view' add to cart button, it works fine as per our theme but not on the main product pages. Is anyone able to help please? I'm ok with editing code when copied/pasted but I have very little coding knowledge.
