I have upgraded to 1.4+ and also upgraded my Apache and PHP to the latest versions. However, my students pointed out to me that the results of a choice I recently put up (after the 1.4+ upgrade) were not being displayed.
I checked, and it said 9 people had responded - so far, so good. I clicked on 'view 9 responses' and saw that only I had responded. I then notced that most of the user images displayed in the 'not answered yet' column were broken links.
I tried cliking on some of the links. Only the teachers reported the correct users. The others reported that 'xxxxxx is not enrolled in this course', with xxxxxx being a random user not enrolled in this course.
Any help on this would be appreciated.
