Versions and comments

Review history, restore an older version and manage reader comments.

When to use

Use this when a change needs to be rolled back, or when you want discussion on an article kept under control.

Before you start

Version history needs the toggle knowledge.version_control (default: on).
Comment moderation is controlled by the toggle knowledge.comment_moderation (default: off); when on, comments must be approved before they appear.
Viewing needs kb:read; reviewing comments needs the review permission.

Steps

Open the article at /knowledge/kb/[id].
Open its version history and compare earlier versions.
Restore an earlier version if the latest edit was wrong.
Read comments below the article; when moderation is on, approve or reject pending ones.
Check the helpful / not helpful votes to see how readers rate it.

Tips & common mistakes

Leave version control on; turning it off stops saving history.
Turn on comment moderation if the article is widely read.
Restoring a version is itself a change, so review before republishing.
Public portal visitors cannot comment; comments come from signed-in users.
