I’ve published by mistake, can I undo?
As long as you don’t hit the “update” or “Publish” button when editing a page, your changes won’t be saved. If you leave the page you’re working on, you’ll be asked if you really want to leave the page unsaved. If you do, nothing will change to the page since your previous save/publish.
But if you’ve already published content by mistake, you can always go back to the previous version of that page. Go to the page you want restored and see the Publish tab on the right. Here it says “Revisions”. Click “browse”, and you’ll see a timeline with all the timestamps that you’ve updated the page. You can go back and forth on the slider, and see the changes that were made and when this was done. When you see the proper version you’d want to restore, hit the button “Restore this revision”. Now you’re back in this version, but it hasn’t been published yet, so hit “update” and the previous version has been restored.
