Since you are using Edge, I am guessing it has been disabled along with the rich-text editor. The reason the rich-text editor was disabled for Edge is that there have been a lot of bugs specifically in Edge and Wikia wanted to save users the hassle of dealing with them while they try to get it fixed.
