Can't update orders Status

Hi,

I try to update orders Status but fail, I even updated the database of opencart,

I manage to update order from pending to complete from phpmyadmin,

But in backend of opencart when go to order history and try to update, it's simply does not work,

Please help.

I have the same problem: I change to shiped (or smth), opencart save to "canceled", and send mesage to customer "canceled"
