I've created a feedback questionnaire and i've used it three times in the same module. The first two times it worked perfectly, but the third time when the students (some students) not all of them, click on the "next page" button it gives an error message: "Error occured More information about this error" Unfortunately, the More information error gives no information.
When I looked at the logs I saw that the "feedback startcomplete" link is missing, so it looks like when the students click on the "start this feedback" link, that is isn't registered that they actually started. I've also got the same error message. I tried it twice and got the same error message. When I did it the third time, it worked. I used the latest version of Google Chrome.
The system is currently on Moodle 2.3. I copied the feedback item and renamed it.
So the error is not constant. It happens randomly and on any browser so I don't think it is browser related.
Could anyone please help?
