I am trying to restore a previously versioned document in a library. When I attempt to restore I get error: the file.docx is not checked out. You must first check out this document before making changes. " How-to articles do not indicate that an item must be checked out first and in fact, checking out or opening an item is not possible from within the version history page.
Thank you for any assistance.
