The versioning system allows you to track changes in your site's discussion group (including stories and pictures), templates and other Advanced Prefs, and revert to previous versions.

Managing editors of a site can use the audit trail to restore older versions of individual messages or preferences.

Configuring Versioning on your site

Click the Prefs link in the Editors Only menu and then choose Versioning. This is where you configure your Versioning preferences.

Versioning Preferences
Enable version tracking for messages and advanced prefs?	Choose whether you want to enable versioning on your Manila site.
Do you want an option to restore previous versions when editing messages?	Display the versioning control form beside changed messages and selected Advanced Preferences.

On the bottom of the Versioning preferences page, you will see a list of Recent Changes to stories and preferences.

Rollback changes to a message

When you edit a message and the preference to rollback changes is enabled, you will see a new form above the editing box.

This form will allow you to restore older versions of the message. Select the version you want to restore to from the "Rollback To" dropdown box and then click the Go button.

Or you can also use the form to delete an older version of a message saved by versioning. While viewing the specified version of the message, check the "discarding latest version" box and click the Go button.

Rollback changes to an Advanced preference

You will see a similar interface to rolling back changes to a message when you make changes to selected Advanced preferences.

This form will allow you to restore older versions of the Advanced preference or discard the selected version.
