Add To Cart Button Stopped Working

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?

Any help will be appreciated.

Thnx. Yup..it started working automatically even for us..It seems it was a Google JS code repository issue as that had stopped working. Once it was up, it was all fine.
