 Description  « Hide
We have found a problem with some tests. The random questions which are stored on the table mdl_question are disappearing, as well as the answers of the students who had responded, which are stored in mdl_question_states, and the grades of the tests (mdl_quiz_attempts).
This is affecting to a lot of tests.

We are using a version 1.6.4 with PostgreSQL.

Luckily, we have backups of the database, but we would like to find out why this is happening. We have thought that it could be the VACUUM ANALIZE done by PostgreSQL.

Cheers

Resolving as 'Cannot reproduce' because I can't, and because there has been no follow-up in the corresponding forum thread: http://moodle.org/mod/forum/discuss.php?d=71457

If anyone can find a way to reproduce this, please reopen.

Hi Tim,

First of all, thank you so much for the attention you paid to our question.

We have the problem a little bit more delimited, or, at least, we think so triste. The problem might come out when we are restoring backups of some of the courses which exist in our installation of Moodle. A curious fact, we have a course in triplicate and we lost the random questions of the same exam in the in these three courses. These questions belong to exams with different ids, and the questions have different ids as well.

As for PostgreSQL: We have already ruled out that possibility, since the same thing is happening to two other installations using MySQL.

As for the improper accesses-> Users' passwords.
Any idea?

Regards, Jesús

I think this is a duplicate of a bug I fixed recently.

Sorry, I clicked the wrong link and closed this rather than resoving it. Hence the fiddling with the status.
