logout/login errors

When I log out of the portal, I get this error in the browser:

Traceback (most recent call last):

TypeError: 'NoneType' object is not subscriptable

In case it makes a difference, I was on the manage_classes page when this happened.

I logged out and logged back in, and things were working normally. When I logged out and logged back in a 2nd time, I got these errors:

But when I refreshed the page, it worked normally.
