Hi, all.
I've bugged Christian about this, but I wanted to throw it out there just in case anyone else has run across something similar.
A couple of the Numbas quizzes they're testing in Blackboard have started reporting this:
It
doesn't seem to happen consistently, but it *does* seem to happen more
often on two particular quizzes from our Advanced Manufacturing Research
Center (AMRC) and more often on machines connected via our VPN as
opposed to our managed desktop (Yoyo) machines.
I'm
not quite sure why we're getting this--the LTI provider and the
PostgreSQL database live on the same machine, so they shouldn't have
trouble talking to each other. One of the theories we're working with is
that these AMRC quizzes are older (apparently a year or more) and there
might be some kind of version mismatch between their SCORM objects and
Numbas or Blackboard.
(As an additional data point, it doesn't seem to happen on our Blackboard staging system, which is on version 3900.17, as opposed to 3900.15 on our production system. I'm not sure if that's contributing to it, though.)
Has anyone seen something like this, and if so, how did you fix it? Thanks in advance for any help/advice.
