I found a problem on my site that may have been not allowing me to use JET PACK. I found that on my woo commerce general setup area, my zipcode for the store was an invalid zipcode. Once I fixed that issue, reactivated Jet Pack, I did not get the zip code error any longer. So it wasn’t the zipcode for the order that was causing the problem, it was the store zipcode. Hope this helps 🙂
I wanted to post that this problem with the Jet Pack pluggin causing an error on the woocommerce cart is still not resolved. Im glad I found this thread. I had the problem today and disabled Jet Pack. It fixed the cart, but no Jet Pack. No real loss.
