I have set up 4 users.
I'm having the same problem, the assign roles page doesn't give any options at all - its completely blank although I have added users. Did you figure out what's happening?
Has anyone found an answer to this? We have had our moodle up and running for over a year with out many problems, but this issue has just been reported to me. Even the built in admin account cannot retreve any users or roles for any context (frontpage - course level).
The mdl_role_assignments table is ok and contains data. We use a mixture of LDAP (fo staff only courses) and manual enrolment. I've run a check on the whole database with MySQL GUI tools which claims every table is fine...
Also, you could try turning on Debugging to see if there is an error message.
I've just got the idea how to view potential users for a course.
Users --> Enrolment Method --> Then you can see "Manual Entrolment option" --> next to "Manual Enrolment" you can see little icon with plus sign with a person, click that and assign system user roll as a student, then go to course and then you can see that user as a potential user for that course, then you can add that user.
Some help would really be appreciated.
Sorry I can't offer any help with this issue as I am unable to reproduce it. Perhaps you could double-check the location for assigning system roles - Site Administration > Users > Permissions > Assign system roles.
My users show up everywhere else, but not on the assign roles page.
just guessing if, perhaps, some of your DB tables have become corrupted and it's preventing you to fetch information from them.
Can you try to check & repair all your tables? Just to eliminate possible causes.
I had over 90 users, and i had teachers all my course. But some day ago one of my teachers clicked unenroll from his course. And i want to add him again as a teacher but ... there no potential users in list???? Where they are gone?
in the users list they are shown, but in potential users they not. how can i assign teacher role again?
I'm also having same issue. When I try to assign a student for a course, I can't see any of the users as potential users. But I have four system users. Please help me.
