We have a puzzling issue. We recently created a slightly customised version of the Manager role, and assigned it to admin and related staff at the category level. This appears to be working fine for courses in the last academic year's categories, and they can view the courses without problem. However, for the newly created courses for next academic year, they are being redirected to the enrolment page and receiving the message "You can not enrol yourself in this course".
If I check permissions for one of these users, for one of next year's courses, the only role displayed is "Authenticated user in System", but for last year's instance "YSJ Course Manager in Category: 2012-13" is also displayed.
The users are shown in the "Users with role" list for both last year's and next year's categories.
We would be grateful for any pointers that help us to resolve this.
We are currently on Moodle 2.3.7.
