I cannot reproduce this at all, same version but with Postgres 15.

Can you enable debug = 2 in application/config/config.php and try again, please? Paste the complete error message here.

Hi.
Thank you for your reply.

Sure:

I'm now using PHP 8.1 instead of 8.2 (but getting the same error).

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&amp;id=34865

Fixed in Release 6.1.5+230626

Hi, the problem seems to be back on Version 6.4.0+231218

Hi, the problem seems to be back on Version 6.4.0+231218

Hi.

Any update on this?
Still the same on the last update 6.4.1+240108

Hi.

Still the same issue, even with a new survey.

The same here:
OS: Ubuntu 20.04.3 LTS
PostgreSQL: 14+238
PHP: 8.1+92ubuntu1
LimeSurvey: Community Edition Version 6.4.1+240108

ok, it's worse with the last update, we get the following right after login:

500: Internal Server Error CDbCommand failed to execute the SQL statement: SQLSTATE[42883]: Undefined function: 7 ERROR: operator does not exist: boolean = integer
LINE 1: ...15 16:38:35' OR expires IS NULL) AND (user_status = 1)) AND ...
^
HINT: No operator matches the given name and argument types. You might need to add explicit type casts.

This is a different error, I believe.

Hi, should I close this bug report and open a new one, or does a report for that already exist?
The error message is the same after creating a new survey, and now with the release 6.4.2+240115 after login.

Thank you for your reply.

We can confirm the issue described in comments 18896:79091 and 18896:79157. We are using Limesurvey 6.4.3, though looking a the current master code on GitHub doesn't make me hopeful this is fixed.

We can however provide a scenario to reproduce this. Adding a subquestion triggers this error, though starting only with the second subquestion.

I think what triggers this is generating a random question id in https://github.com/LimeSurvey/LimeSurvey/blob/master/application/controllers/QuestionAdministrationController.php#L722 and then trying to get a question object for this is https://github.com/LimeSurvey/LimeSurvey/blob/master/application/controllers/QuestionAdministrationController.php#L830. MySQL doesn't care a bit about any garbage it is passed (at least in the default settings) and will happily accept new12345 as an ID to search a question with (and I think it will just drop the new part because it's not a number and keep 12345, but that's another issue), whereas PostgreSQL loudly fails when passed a string value for an integer field (new12345 for qid).

Most astonishing is that in that case at least the random issue is called to get an empty subquestion object with https://github.com/LimeSurvey/LimeSurvey/blob/master/application/models/Question.php#L1654, which doesn't seem to care at all about any attribute from the object it is called from, though I am not a php developer and might be missing something.

I hope this analysis will help bring a resolution for this issue forward.

I can confirm, that with version 6.4.6 the bug has gone in our installation.

We are on version 6.4.5 and this problem does not happen anymore.
