Fatal error: Call to undefined method VirtueMartModelOrders::getInvoiceNumber()

[gordonmichael]

I am using VM2 2.0.10 and Joomla 2.57. I can place orders but when I go in administration to check "Orders" I receive this message: Fatal error: Call to undefined method VirtueMartModelOrders::getInvoiceNumber(). I have no 3rd party plugins. I can place an order with PayPal or Authorize.net and they get processed. I should also mention that the Order List works.

Solved: I reinstalled latest update and it cleared the problem.
