I have got the latest version of smith cart installed on my website, however once a transaction has been completed by Paypal, it returns with the following error message.
A critical error has occurred.
Column 'RemoveDnnRole' does not belong to table _ProductList.
Checking in the database and the transaction has updated to paid status, but doesn't return the customer to the confirmation page after paypal.
Please help, as i have currently the website down.
