I have updated my WP to 2.8 today. When I try to edit or add new posts i get the usual text editor but the existing posts is only shown with white text color on a white background in HTML, so I can only see it if I mark everything. If activate "Visual" I get the HTML formatted post shown and the text editor-bar is missing.
How can I resolve this?
Please see this picture for an visual explanation of the problem:
