I have changed the status of an order from being Cancelled to an active status, and I cannot change the Approval Status of the order?

PRESSERO > *Pressero FAQs
If you are editing an order in Pressero admin and have changed the status of the order from Cancelled to an active status and you are unable to change the Approval Status of the order, then you need to close the order and re-edit it to be able to change the Approval Status.
