Access the Page Versions list by following the steps on Accessing Page Versions.
Check the box next to the Version you want to approve and publish.
TIP: Remember that you can easily view previous Versions first.
NOTE: Boy, that “Version 3” in the Comments column is spectacularly unhelpful, isn’t it? As we discussed back in Saving your Pages, working with Version is far easier when you put in good Comments when you save your work!
Press the Approve button (thumbs up icon).
The checked version of the webpage is now approved, so now site visitors (guests) will now see that version.
