Bingo! That did the trick! Thanks for the tip!!
I’m having the same problem. You said yours was caused by your anti-spam plugin. Which plugin in particular are you talking about?
I’m having the same problem under WP 2.1.3. I also have the WP-Polls and reinstalled it with no problem. I created a user who only had “Editor” priviliges and I was able to log in under that account and use the Visual Editor just fine. But as soon as I log in as an admin I lose it again.
I’ve tried most of the fixes above short of downgrading. Any other ideas?
