I was having this problem…here is what I found. I went to the /wp-includes/js/tinymce folder and saw that the directory structure did not upload over FTP correctly. Many folders were missing, so I manually uploaded them individually…for instance, the themes folder was missing, the plugins folder was missing, etc…Only the langs and utils folders and the base files were appearing.
It should look like this:
/var/www/html/wp-includes/js/tinymce
/langs
/plugins
/themes
/utils
blank.htm
license.txt
etc, etc etc
Im not sure why this seems to be a problem. Ive got it working great now…and it was simply missing folders. I tried several times to upload the entire tinymce directory, and every time, it failed to upload several folders.
Compare your local wp file structure to your servers…
Hope that helps!
