One of the users within a website I control let some other webmaster into our Admin Dashboard to install a security plugin (called "WP Lockup"), which, among other things, adds a prefix to our wordpress database's tables.
When I checked the WooCommerce Orders listing I found that most parts of our Orders are fine (their comments and customer notes have been preserved), except their statuses are all set to 'pending'. However, within the Order listing page in the 'Show all statuses' dropdown menu, only 3 items are designated as being 'pending'.
I went into an order that I know had been completed, reselected 'completed' and then saved the order. The previously mentioned dropdown menu now lists "completed (1), pending (3)".
I have no idea what to do, we need to have our Orders' statuses restored. Might there be a way of restoring them by looking to the Orders' comments and determining which of the statuses it should be set to, like the below?:
Order status changed from on-hold to completed. =>
EDIT: I figured out that the issue had been caused not by the security plugin, but upon deletion of the Jigoshop plugin (which we had used previously).
