Magento 1.9 - Uncaught Error: Call to a member function canCapture() on boolean in

Question

Over the weekend, a product purchase seems to of triggered an error. The result of which means the orders page is displaying on the one order, with all previous orders being no longer accessible?

The following error message is displayed in the Default field of Sales / Order page.

Fatal error: Uncaught Error: Call to a member function canCapture() on boolean in

Looking at the line app/code/core/Mage/Adminhtml/Block/Sales/Items/Abstract.php:481, you will see $this->getOrder()->getPayment()->canCapture().

It seems that Magento can not retrieve the payment of your order. The result of $this->getOrder()->getPayment() should be an object and is a boolean : that's why an exception is thrown.

You will have to debug to understand why you don't have any payment for this order.

(First step : what is the payment method assumed for this order ?)
