Page Builder’s history browser is your personal safety net. It allows you to jump forward and back through changes, restoring any version of your page since your last save. To open the history browser, click on “History” in the main Page Builder toolbar.
Let’s say, for example, I accidently deleted the slider at the top of my page. That’s not a problem; you can see the change is in the history browser. Click on an event to see what the page looked like before this event occurred.
You can check that you’re restoring the correct version by looking at the live preview on the left. Once you’re sure, click on “Restore Version” to load this version back into Page Builder. You’ll also notice that there’s a “Version restored” event in the history now. This allows you to restore the page as it was before you restored the old version. So you can always get your changes back if you decide you want to keep them.
