Add To Cart Redirects & Adds too many products

[KVDommergaard]

Hi,

I'm having an issue with my checkout flow on www.zpey.com.

When users press on Add To Cart it - most of the time - adds multiple products to the Cart instead of just 1. Also it takes them directly to checkout - also sometimes - which I don't want.

I'm using the Modular Theme.

Hope you can help me out.
