I've recently upgraded from 1.5.2 to 2.0.4. Before upgrade I took care of getting into use new versions of plugins which also support wp2. Upgrade went Ok without any errors and the site is up'n'running fine.
Except ... that I can't see the rich text editor when starting to write new article. Yes, I have checked the option "on" in my own user profile, but still it is not there.
In database table wp_usermeta users meta_key rich_editing = true.
However, one thing I'm suspecting is that I had usermeta plugin (ver 0.4) installed in wp1.5. Not using it any more. Can this be the cause for the problem? In usermeta's documentation (http://dev.wp-plugins.org/wiki/Usermeta) it is stated that versions 0.1 and 0.2 are problematic, but newer should be ok.
If it is not usermeta, what could be the problem?
