Hi, Rick.

Thanks for reporting this.

Have you tried to create new Gradebook items and locking them? It would be good to know if this is a problem with the Gradebook or the result of the restore not functioning properly. If you do encounter the problem in new grade items, please supply replication steps. If it seems to be a problem in the restore, bump the Security level of this bug up to Minor and attach your backup so we can try to see what's going wrong there.

Hello Rick. Is it practical for you to turn on error reporting on this site? Here are the instructions on how to do that. http://docs.moodle.org/20/en/Debugging#How_to_turn_on_debugging

That would be great if you're able to do that and see if you get a more informative error message.

Hi Michael and Andrew, I have more information to share with you.

By experimenting, I discovered that this problem only occurs with "Quiz" grade items, not with Forum, Assignment or general grade items (items added directly, such as an Attendance item. The problem occurs in newly created courses, or imported courses.

I did turn on debugging, and here's the message:

Fatal error: Class 'mod_quiz_display_options' not found in /home/rjerz-vs/public_html/moodle2/mod/quiz/lib.php on line 615

Along the way, I discovered that when a quiz is created, there is no dialog box that allows me to put this into a specific category. I don't know why. I will look around and maybe post another "bug" tracker item.

I've added Tim Hunt as he is the master of all things quiz just in case he has any thoughts.

The missing 'Grade category' option on the quiz settings form is already reported as a separate bug.

I guess there is just a missing include here. I'll fix it.

I just installed the latest 2.1 (Moodle 2.1.1+ (Build: 20110803)), and this problem is still present.

In debug mode, here is the error.
Fatal error: Class 'mod_quiz_display_options' not found in /home/rjerz-vs/public_html/moodle2/mod/quiz/lib.php on line 615

I made a short video to show you this problem.

Remember, this problem only happens to "Quiz" items in the grade book.

Rick, that is not surprising. Look at the status of this issue: Status: Waiting for integration review. Resolution: Unresolved.

Next week the issue will go through integration review and testing, and then, all being well, the fix will be included in the Moodle 2.1.1+ weekly build.

Tim, thanks. I am still getting used to the tracking system. I'll wait.

Thanks Tim, this has been integrated now

Locking and unlocking quiz grade items now seems to work as expected.

Sent upstream and closing, many thanks!

Eloy (and others),

I hate to bother you with an administrative question, but I was the one who started this tracker item.

I am trying to find the "road map" of how tracker items are tracked, but I can't seem to find it. For example, I have watch the "Status" progress on this item, but was never sure how many more steps were involved. I notice that this item has been fixed, and its status is "Closed". Does this mean that it is now in the current download of Moodle 2.1+?

I really have appreciated everyone's attention to this issue, and am very impressed with the overall tracker system. Keep up the good work. This is what makes Moodle better than the other LMSs.

http://docs.moodle.org/dev/Process should explain.

Closed means it that it is now in 2.1.1+ (and also in the development version that will become 2.2)
