This may sound strange. Because it is. I recently upgraded to WP 2.0.4.
After posting ten times, I suddenly was no longer able to access my dashboard, which appeared totally white and um blank. The rest of my blog appears and functions normally.
My problem is just on the back of the house WP-Admin side. Through my FTP, I went back and deleted the WP-Admin folder, then dropped a new folder in and still had the same problem. I checked all its contents and all the php files seem to be there.
Anybody have any ideas? Thanks.
