How to configure Page Status
When using online proofing, you can enable Page Status (available in the document proof viewer only), allowing users to assign a status to individual pages. To enable this feature, follow these steps:
Navigate to Site Configuration → {Module} → Proofing and Comments.
Click Edit Settings.
Locate the option Enable Page Status and tick the checkbox.
Depending on whether Limit access to Comments and Page Statuses by is set to Access Rights or User Groups, you can define who has access to each status value. The system supports three status states: No Status, Green Status and Red Status. A custom label can be assigned to each state to align with your business requirements.
Click Save to apply the changes.
