I have not made any amendments to any code, but when I try to test out the payment process using PayPal Website Payments Pro (UK) I get errors. I am using V.19870 of Magento.
If I try to check out using Express method I get the following error:
Fatal error: Call to a member function getResultCode() on a non-object in /mysiteroot/app/code/core/Mage/PaypalUk/Model/Api/Pro.php on line 207
And this occurs on URL: /paypaluk/express/mark/
Any ideas as to what this could be?
