The real source of the problem?
Just like the case above, chances are you used your browser’s “Back” button during the course of a Online Banking transaction. To avoid the message, always use the “Go Back” and “Continue” navigation buttons provided by the Online Banking Application. To recover from the error message, it will be necessary to sign on to Online Banking again from scratch. It would be a good idea to confirm that the transaction was not completed before performing it again.
