Hi again from Oulu, Finland,
This frustrating problem is still on. It started with older versions but update didn't help.
I have set all activity completion settings on all levels site, course, activity (hopefully) and students can mark/tick their activities as completed
On "Course administration > Reports > Activity completion" all I get is an error message:
"There are no students on this course or group for whom completion information is displayed. (By default, completion information is displayed only for students, so if there are no students, you will see this error. Administrators can alter this option via the admin screens.)"
However, there is students on the course and I have tried with a new course and a new student accounts with same depressing results. - If I remember right this worked some months ago, but not anymore.
Server cron job is ok. That is the latest thing I have checked but now I am out of ideas. Btw, what are the options on the error message which administrator can alter?
Statistic report work OK and I can see that students have been active etc.
No matter if I make a totally new course with a new students and turn on all settings and make tests. -Still this error message.
-Maybe You can help.
