We have upgraded Magento version 1.7 to 22.214.171.124 but when I click on "place order" button, this error shows "There was an error processing your order. Please contact us or try again later", while choosing cash on delivery payment option.
We have enabled log file and this shows this error:
'Mage_Core_Exception' with message 'Invalid block type: Mage_PaypalUk_Block_Link_Shortcut' in /data/flavorwest_magikcommerce/app/Mage.php
We do not use the default theme, but we have tested it on the RWD default theme but same error shows
