Updates notifications missing


I just realized that my wpmudev updates are not working.

I was checking to see if the Network 1.7.5 and Scholar 4.2.6 themes were OK with WP 3.3.2 when I noticed that my themes were not current. There are also no notifications of available updates.

I also noticed that Pro Sites is at 3.2 but I'm at 3.1.3 and there have been no update notices.

Any idea what is wrong?
