I’m running Magento 22.214.171.124 and I’m getting this error when trying to access orders in the backend:
Fatal error: Class ‘Mage_Adminhtml_Block_Sales_Order_Payment’ not found in /home/roccohom/public_html/site/app/code/core/Mage/Core/Model/Layout.php on line 462
There aren’t any problems on the frontend - the customer is able to view their order history.
I’m not sure how this problem has arisen (or whether it’s been there since the install) but the only modifications which have been made are to the template and skin files - nothing which could of caused an error in the backend.
Is there any way that I can debug this error in more detail, or has anyone had the same issue? Line 462 of Layout.php reads:
$block = new $block($attributes);
I’m stuck as to what might be casuing this. If anyone has any ideas it would be much appreciated!
