[Building Sakai] Exception in Tests & Quizzes when viewing "settings"

[Joshua Swink]

Hi all,

We're getting an exception when viewing the settings in Tests &
Quizzes. It happens consistently with one specific course site that's
being used by a long-time instructor. The exception comes up even for
new assessments that we create in the site. This is a new course site
that was created for the fall semester. It isn't happening in other
sites. We're using Sakai 2.6.2.

Can anyone think of a cause or solution for this?

The exception is as follows:

org.sakaiproject.portal.api.PortalHandlerException:
