I know that this post says resolved, but many people like WP-Insert and use it frequently. I just upgraded one of my sites and had the same problem with the Menu sidebar missing. I just deactivated WP-Insert and it is back, but I don’t like this update if its going to do that. I will not upgrade my other sites to 3.2 until this problem in conflict with some plugins shows resolved. It stops important work and it is an annoyance.
