Whenever a page is deleted in NiCE Knowledge Management, the page is automatically retained in the NiCE KM control panel, allowing administrators to preview and restore deleted pages.
Only administrators can restore and delete pages. Once a page has been permanently deleted, it cannot be retrieved.
How to restore deleted pages
On the NiCE KM toolbar, navigate to Site tools>Control panel.
Under Maintenance & History, select Deleted Pages.
Preview the page to be restored by clicking the Restore link.
