I am using Moodle 1.9.2+, recently upgraded from 1.5 (I think). When I click on Participants in the People blocks in my courses, the names of the participants are not visible. The courses appear to include the correct people, and both Participants (students) and Moderators (teachers) show up, but the name is not there. Other fields are present - profile picture, city, country and last access - just no names.
Any help appreciated!
