Hello Guys,
After upgrading from version 2.7 to 3.2, I've noticed that during quizzes, for some questions, the answer would be checked automatically. The question preview works fine, but the problem occurs during quiz attempts. Any thoughts on what is causing this error. I've had to disable the quiz module because of this.
Thanks in advance.
Is this just using the core multiple choice question type or a plugin?
I'm using the core multiple choice.
I tried previewing a quiz on a development machine and it works fine. The only difference I can think of is, when I went into the database (quiz_attempts table) and changed the status of some hanging quizzes column from abandoned to finished. I'm not sure
I would suspect that that has a lot to do with it. If you take a look at the table layout for the quiz, there is nothing simple about it and so an innocent change of status could mess a bunch of stuff up.
How about you share why you went into the database in the first place? Was there an error coming up somewhere?
Sure. A couple days before, our server crashed and we had to migrate to another server. I restored the database from an SQL backup in a new MariaDb 10.1 system. The problem was noted then. I then did the following.
So did you upgrade at the same time as you migrated or did you get up and running first and then see the issue following the upgrade?
Perhaps try a fresh download of code and see if that resolves it.
Can you show a screenshot of how the quiz looks?
First, I upgraded from 2.7 to 3.2, then migrated, then upgraded to 3.2.1 after the migration. I'll try to download a fresh copy ASAP. I've attached an example. It shows the preview of questions 7 and 8 of a one page quiz. No answers were selected by me.
So that isn't showing the correct answer, just the first answer? Is that what it is doing? Have you tried clearing out all your caches? I wonder if you are just getting some cached version showing up?
I "purge all caches" then ran the preview again. It is still checking options, but not necessarily the correct one. It seems to be checking A and B. I've attached a sample.
I still think this might be caching. I would suggest actually deleting out the cache and local cache folders from your moodledata folder (they will be recreated) and also clearing any cache on your computer too. Not sure where you are hosted but if with a host, they may well have a cache too.
Interesting. I guess you could check the database for that field allowing null values and then update as necessary. Maybe Tim has some ideas on this?
Thanks Emma,
I will take a look at it in the morning and give an update.
Hello,
I upgraded to Moodle3.2.1+ this morning. That went well. I'm still the same problem. What's bugging me, is that when I preview the individual question, preview.php does not add any checks, but, when I preview the quiz attempt.php does add checks.
I'm thinking that there may be that a condition may not be evaluated properly somewhere. Just a thought...
