I have created a New User as an Editor. When I go into the editor the window is blank except for red wiggly underlines. The text can be selected but it's white on white. The text in the window is html but whilst in Visual mode. HTML mode can't be selected. I have disabled the plugins but still not working. When I log on as an Administrator I can see all the content fine, it's just when logged in as an Editor.
Does anyone know how to solve this please? Thanks.
