We are on cs-cart v 4.7.3. The Add to cart button suddenly stopped working for a certain category of products. And this happened on even all our test sites which was a replica of the live site but hosted on a different server.
When I checked Google chrome dev tools, it doesn't show any error. Can any one help me in identifying the issue?
This is an test URL that can be used for repeating this issue.
Any help will be appreciated.
thnx
