There's nothing to do about "MediaWiki:Sitenotice-id" because it doesn't exist – you get the same blank history and missing edit button with any nonexistent MediaWiki page. What you're probably looking for is "MediaWiki:Sitenotice id" (example on my wiki), which is used to update "MediaWiki:Sitenotice" (example).
