When I try to edit the section summary of any course section/topic, everything seems to work fine and there are no errors. However after clicking Save Changes the page goes back to the cource section and nothing has changed!! ..it's still how it was, I click on the Edit Summary icon again and the old text/html is back there and none of what I typed was saved.
It's really strange and right now I'm pretty clueless as to why this is happening.
I'm even able to edit the Section Name, but the Summary just won't change.
Any ideas???..
