How to Use “Post Revision” to undo changes in WordPress

To undo changes in WordPress with Post Revisions, please follow the steps written below:

  • When writing a WordPress post on the post edit screen, you may have observed that there is a Metabox, tagged “Revision” under the ‘Document’ menu, which shows how many revisions have occurred on that page.
    Note: This option will only appear, after you have at least two different versions of the post, i.e. if you haven’t modified the post before, you won’t see revisions button.
  • You can find ‘Revisions’ on the right side of the post editor screen. Click on it to go to Post Revisions screen, here you will see the latest revision of the post with a scroll bar at the top, through which you can slide to move between other revisions. Each time you move the slider, you’ll see:
    • A version of the previous revision, on the Left side.
    • A version of the selected revision, on the Right side.
  • Changes made to each revision will be shown there. The added content is highlighted in “Green” and the deleted content is highlighted in “Red”. The name of the user who made those changes will appear at the top of the page along with other information such as editing time.
  • WordPress will also show if an edit is a manually created draft or saved via Auto-save.
  • Use the ‘next’ and ‘previous’ buttons to move around revisions and make changes according to your need. So this is how you can UNDO changes in WordPress with Post Revisions.

Comparing Different Revisions:

You can compare two versions of your post. However, they are sequential revisions, meaning that one happened after the other.

  • If you want to compare two different drafts (non-sequential versions) of the same post, click on the box at the top that says ‘Compare any two revisions’ which will split the scroll bar button in two and you can use the slider to move each button to different revision and compare the revisions.
  • If you want to restore a revision, you only need to click on ‘Restore this revision’ or ‘Restore this auto-save’ button. When doing so, WordPress will restore that version of the revision as your current post or page revision. Also restoring to an earlier version will not remove any of your latest versions from WordPress. As an alternative all revisions will be saved in the WordPress database as another revision.
