While you and your collaborators are editing your site, you can keep track of changes (and of the person who made them), and even revert to an older version by using 'Revision history.' From your site, click More in the top right of any page and select Revision history.
On the next page, you'll see a list of the site versions, the date and time each was last edited, and the name of the person who made the changes. You can also compare two revisions at a time by selecting one version and clicking the Compare two versions link.
If you change your mind about the most recent edits you or your collaborators made to the site, simply revert to an older version. Here's how:
- Click any version from the list. Optionally, while viewing a particular version, use the Compare two versions link to see the differences highlighted.
- After returning to the 'Version history' view, click the Revert to this version link next to the version you'd like to revert to.
Your document is reset to the version you selected. The replaced version is also included in the version history and can be restored as well.
