I never could see the default visual editor in WP 2.x :-(
I had tried all the tips posted in all the forums, but nothing worked for me. Now I upgraded to WP 2.1 in the hope that I would finally could use the RichEditor but no... I still can't use it.
I get the two "tabs" to switch between visual and normal editor, but actually it does nothing for me, since the visual editor never shows.
Curiously, if I install a third party WYIWYG editor plugin, it works fine.
Any ideas?
