I love this plugin but recently a client of mine says it just stopped working. It has been working fine for 3 months and just the other day the add to cart button does nothing.
The website is - http://www.flickskidsbooksandthings.co.uk/merchandise/
Once you click on the add to cart button it used to show it on the payment page once you go to that page. But now, nothing happens.
Any help and advice would be much appreciated as I have checked and cant find anything that could be causing this.
