 Hi, this is Monica Shingle-Jones and I'm going to show you how to undo an editing mistake if you make one. And I'm here on Ijeoma Olo's biography and there's a mistake here that background should be a major header and there's a citation that is missing that used to be there. So I know this because I go to View History and I can see that earlier version of a page. So this moved citation was a mistake. So what I'm going to do is I'm going to click on the earlier version of that page. You just click on the timestamp and this is the version of the page that I wish to restore. Yep, that's right. So here we have the citation and then the background is a header. Great. So now you just click Edit on that old revision. You don't actually need to edit anything because you're just going to save this as the most current version. So you click Publish Changes and I'm going to write in the Edit Summary Restored Correct Version with header and citation in place. Now I'm going to click Publish Changes and I'll look on the article home page here. The previous version of the article is restored. The citation is in place and the background is there and that's how you do it.
