comments worksheet shows blank page

[xris_xcess]

In our school the teachers write course personality reports twice a year for the students, and I'm was looking for this funtionality in schooltool. You can do it through a comments in a worksheet, but this has to be deployed schoolwide.

I did this and get a new tab in the gradebook, but when I select it I get a blank page.

I the server error log I see:

---
Sat Sep 6 12:26:21 2014 unauthenticated, sb.person.user1, User1,
KeyError: u'3.6.1/ckeditor/ckeditor.js'
--------------------------------

I also tried with the manager account and get the same result

I'm running ubuntu 12.04 and just upgraded from 2.6 to 2.8 through the PPA
