Update: Some wikis are reporting that the Rich Text Editor isn't displaying at all. We've found that this is usually because of a conflicting error on the wiki's custom JS pages. If you're using a wiki with this problem and you're unable to find the error, please report it to Special:Contact and include a link to an edit page that isn't loading for you. Thanks!
