Sorry - forgot to add that I logged in as the teacher, then clicked Gradebook at the top and this is the error I got.

[Tom Hoffman (tom-hoffman)]

Have a look at this when you get a chance, Alan.

[Alan Elkner (aelkner)]

I will be fixing this bug very soon, but in the meantime, the teacher can solve the problem by going to his/her home page by clicking the Home tab, then clicking on any section and then clicking the Gradebook action link below the red bar, not the Gradebook tab.
