I've just had a strange experience on one of my blogs. I'm using Firefox 220.127.116.11 on the Macintosh. On one blog, I no longer get the rich visual editor on the Write Post and Write Page sections. All of the appropriate "Use Rich Visual Editor" boxes are checked on.
This isn't directly browser-related, as another WP blog does show the rich visual editor, and the problem blog used to (and no config changes since it used to).
Any thoughts? Thanks in advance
