Hi,

We tested this and your site works correctly – it opens a new tab and does not add anything to the cart.

Do you know what kind of browser and OS you are using?

Thanks

hi
Many thanks for getting back to me
You are right it has been fixed
I am going to explain further in case others could benefit
Initially it was adding external items to the cart
On this site there is a woo-zapier with restAPI and as you pointed out this could created unexpected results
To test if this is the issue I deactivated the woo-zapier plugin and yes it was the issue then I reactivated it but did not check it again assuming it will continue to be an issue
but it seems deactivating it and reactivating it sorted it out!

Is that possible?

I am glad it worked out, depending on how the other plugin integrates it is possible it can interfere
