Cannot add questions to quiz from question bank

Cannot add questions to quiz from question bank

HI,

I am using 2.8.5+ along with original theme. It worked well for a day or two but suddenly when I want to add a question to a quiz from the question bank, I can no longer do so. The spinner icon just goes round and round and nothing happens. If I go to the question bank directly the questions are there, I just cannot get to categories or their questions from within a quiz. When importing question to the question bank, they also displayed sluggishly.

I don't know if this related, but I was using 2.6 and the question bank would not "shift" to different categories when clicked on that in quiz mode, which is why I upgraded in the first place during the school year. However, now I still cannot add questions to a quiz from the question bank.

Any ideas would be greatly appreciated.

Thank you.

At which point in the process of adding a question from the question bank do you see the error?

Which web browser are you using, and are there any JavaScript errors reported by the browser?

Can you turn on Debugging in Moodle, and see if that leads to any error messages being displayed?

Thanks Tim. The error occurs simply when I click on "add question from question bank" to the quiz. There are no debugging errors. There is a Javascript error which is displayed below. I did find a workaround in that I can add a "random question" from the same category and then I can go back and add questions normally. Weird. I tried this in multiple browsers and computers.

That 500 internal server error will be accompanied by a debugging error, but you can't see it because it is an ajax request. You need to get Moodle writing the debugging errors to the server log, as well as on-screen (actually, that should happen anyway) then find the error from the logs.

Does this look like what I might be looking for?

Probably not. That seems to have nothing to do with the quiz. It does seem to relate to PHP staring, and being unable to load a certain MySQL library, which would affect every request.

However, it does seem like you have found the right file, probably.

Set Debugging to DEVELOPER but leave Display debug messages off.

Open the PHP error log and see what the last message is.

Then, do what you were doing in the quiz that did not work.

Then look at the error log again to see what has been added at the end.

Hi Tim,

I still didn't get to the PHP logs but I did look at the general server errors and noticed this one:

Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp for...../theme/yui_combo.php (I took out some of the path).

I contacted the host and they said: 


It looks like your server was running out of memory. I'm seeing that your MySQL configuration was set up for a server with more memory. I have adjusted the settings to more appropriate levels.


Since then it look like things are working properly.

Good detective work! Let's hope that has solved the problem.
