Shopping cart “loop” issue after upgrading to 1.9.3.6

[mardz]

Hello,

I just upgraded from Magento 1.9.3.2 to 1.9.3.6 with the connect manager, now there is an issue with the Shopping cart.

After entering the customer address and clicking the "Next" button, it redirects back to the shopping cart view. So it's impossible to complete an order.

Also, "system.log" and "exception.log" show nothing particular beside a small PHP notice.

Is there a way to fix/debug this ?

I also inspected the form with my browser and the "formkey" field is not missing.

What could cause this issue ? Is there a way to debug/fix this ?

Thanks!

Hi @mardz,

Maybe you can start checking what is happening at \Mage_Checkout_OnepageController:rogressAction and also if the failureAction method is being called?
