Users can unretire a document category, if needed, but only the latest version of the category can be unretired. If there is an active version of this category, a previous version of the category can not be unretired.
For example, if there is an active category with a few previous retired versions, these previous versions cannot be unretired as there is an active version.
Unretiring a Document Category
Click 'Settings >Document Categories'. Find the latest, retired version of the document category on the table. Click on the category name.
Under the 'Actions' button, click 'Return to Active'.
Once clicked, a success banner will appear when the category returns to an active state.
