I upgraded to 2.5. Everything seems to be working fine. However, I would like to be able to use the new "no-distractions" writing option in the post editor. Unfortunately, I can't because there is no visual editor tab in the Post editor. The HTML editor tab is also missing, but the Post editor does show the html of the post, and has the old [b][i]... buttons on top. So apparently I'm not in WYSIWYG mode.
Any ideas on how to get the default editor to show up, instead of this now outdated "Advanced" editor? I tried to change my settings in the Settings, but the "Advanced editor" option no longer exists there.
