Over the weekend the Simple Staff List menu item disappeared from the WordPress backend menu. We can still edit staff members through: /wp-admin/edit.php?post_type=staff-member URL though can't access anything else such as groupings.
Any suggestions? We have deactivated a few plugins (the site is live so we can't debug the plugins currently) that are related to custom post types and taxonomies, though the menu item is still gone.
Please advise. Thank you.
