Post & Page Form Show White/Blank & No Tool Bar Selections

[Ledbetter]

The problem looks like it is caused by Wordpress 2.8. I now have the Lifestyle Theme 4.0 on 2 different websites, at two different hosts, both sites show the post & page form area as white in edit or write area (with tool selections above window missing also). I can highlight and then see the text in "Visual" window, but it appears to be the same code as the "HTML" window, not plain text.

I have many websites, so I checked others. They were fine. I upgraded one other site to Wordpress 2.8 (to test my theory). This site has a Revolution Magazine Theme. It viewed correctly before the upgrade to Wordpress 2.8, but now it has the same problem as the others.

If any of you have Lifestyle 4.0 (or other Revolution Themes) and the latest Wordpress 2.8, please check some of your posts or pages in edit, or in add new ... can you see the post or text in form/window or is the window area white?
If I am correct, when any of you update to Wordpress 2.8. You may experience this same problem.

If there is any additional information, please post a reply.

Thanks!
