Things May Change
Maybe you made a mistake. Perhaps you left out important information or something happened that makes the current information irrelevant. PSB allows to make the changes to your content and to keep track of both the original version and all of the revisions you have made.
To revert to a previous version of a page:
Log in to your site. Click Manage, and then click Content. Go to the page you want to revert and click the “Edit” link. Each version includes a date/time stamp as well as the username of who created the version. If a revision message is included, it will appear under the revision date. Locate the previous version you want to revert to and click Revert in that row. If you need to confirm the version, click on the hyper-linked date/time stamp to preview the page before reverting.
You will see a new screen asking if you’re sure you want to revert to this version. Click “Revert” or “Cancel” to proceed.
