Visual editor not working when crafting pages under "blog" category
I've been adding pages under the "blog" category which I have renamed "assets". Yesterday, I was adding pages and everything was working fine. This morning as I've gone back to edit those pages and add new ones, I've found that the visual editor is missing and the "pages" page is only allowing the very basic features of the HTML editor. I can't seem to toggle between them. When I toggle, I get the HTML features on the HTML editor and on the visual editor toggle I get a small blank area where the visual editor controls should be.
I've checked under my user name to make sure that the "disable visual editor when writing" check box wasn't checked and it was not.
