True Rick,
I would not really make her delete all 2993 topics. I'm with you on her recreating the course but for now my solution is this 7 step process I sent her. Before you read that though, Jim Judges fastest solution at tracker here is simply type the number 7 in her case where he says
The latest versions of this plugin for 3.4 and 3.5 have put back the option to control the number of sections ('numsections') in the usual place in course settings
Well I don't see it in my settings even after uninstalling and reinstalling this plugin. (v 3.4)
In liu of that, here's my easiest solution to help her for now:
1. I hide the original course
2. I create a new course called same with name copy on front hide it too.
3. She imports her 7 topics to it
4. She enrolls all names from original course into new course
5. She create new BBC Ultra (specific to our Moodle for conferencing with kids)
6. I un-hide new course and rename original to say OLD and take off the word copy on new one.
7. in a month or so I delete the original course when she is sure she has everything.
My time in this is about 5 min but hers be a bit more and may confuse students for a bit.
Jim's solution is more elegant and fastest and would really benefit me for the inevitable next teacher who does this. Any idea why I don't see num sections "in the usual place". I attached a screenshot of my entire settings for collapsible topics.
Thanks.
