I'm having the same issue with applying this update. I've confirmed that the "contents_insert.php" file uploaded with changes to the server. But I don't see anything change with the html editor. It still is missing the "Styles", "Font Format" and "Font Name" elements. Sounds like the same problem already reported. Whatever solution was found with the above reported issue would be nice to have appended to this thread. I have a feeling it'll be the same solution for me too.
