I have the same error with PayPal module. I have latest version 1.4 of Presta Shop and I tried to test my shop by buying an item. All works fine but when I click on the Paypal to choose this mode of payment I get this error message: [an error occurred while processing this directive] on this page: /modules/paypal/payment/submit.php Any help would be appreciated! Thank you! * I also posted this in Bug Report!
