@Allwell987 Ah, this isn't actually a typo. The name of the article is "Managing your repository's settings and features," but we don't put apostrophes into the URL. That's why the linter is complaining about the path being wrong. I'm going to close this one since the fix isn't needed, but thanks for taking the time to open it!
