Looks like you ran into an active bug possibly. Take a look at: https://tracker.moodle.org/browse/MDL-63231
Does it happen only with SCORM activities? Does the teacher have moodle/course:changesummary capability? Your site might have disabled it and it will give that error. See Paul Martin's post here: https://moodle.org/mod/forum/discuss.php?d=374099#p1510686
We are aware of this bug and ran into an issue this bug causes with needing to change settings in an activity and being unable to do so. We are not sure if it is related to our problem of not being able to add a new SCORM activity or change the url within a previously created SCORM activity or that is a separate bug?
We can add the other activity types without error, it is just unique to the SCORM activity for us.
It is not a permissions issue as we use Moodle in a corporate setting and don't have Teachers per se, the staff that create and maintain our course materials are all Administrators in our db.
I did check the access to the coursesummary for that role and it is checked.
Wish I could help more but I'm not sure. Though, I would say that changing a previously created SCORM activity does count as changing settings in an activity though, which would trigger the bug and the SCORM activity does always deal with the moodle file system I think in ways that other activities don't.
