Problem with checkout:"Your shopping cart is empty" after entering payment details

[steveirl]

Hi

 

I'm having some trouble when checking out with the Stripe module. After entering payment details I get the following message:

 

Your shopping cart is empty.

 

The Prestashop version is 1.5.6.1

The Stripe module is version 1.4

 

Server is Windows 2008 / IIS7

 

The Stripe account is in test mode and the the module is configured with the test keys

 

I've tried disabling friendly URLs as suggested in some other posts.
