after upgrading from 1.8.4+ to final 1.9 I have the following problem:
I am teacher of many courses on our Moodle. Most of them I can access without any problem (visible and hidden courses).
But there is one special course, category is hidden, course is hidden, password is set, and I am teacher in this course. Every time I try to access this course, I get the message, that login for participants is not possible right now.
After rechecking, deleting me as teacher and re-adding myself again, no change.
This course is not shown up in the my-moodle and also cannot be accessed directly by using course-id.
As administrator I can access this course without any problem.
