The Paypal plugin is working fine for orders that are created and paid for at the time. However, I recently switched in the option to pay for orders at a later date via the user menu and when clients go back in and pay for a previously created order, no payment notification e-mail is generated and, presumably because of this, the order remains as 'created', rather than being changed to 'confirmed'.
Is this a setting in the back end that I have missed?
