I have just updated from 1.6 to 1.6.1 (and upgraded from wp 3.3 to 3.3.1 so there may be issues there) and have found the following problems:
When attempting to either edit an old page, or create a new page, the “HTML editor” bar is blank (Visual editor bar is OK) Also the “upload/insert media” function doesn’t work (i.e. clicking on it does nothing.
This problem only occurs in page edits, not post edits.
Has anyone else seen this? And if so, how can it be fixed? I have temporarily reverted to 1.6 and wp 3.3 to get around the problem. The blog is at baldric.net.
