I have limesurvey 3.7.3 setup with postgresql 9.5
One survey with 2 question groups and several questions. The question group order is different on postgresql and mysql. See the screenshots, on postgresql, the later added group ( here is "General Questions") shows on the top, but on mysql, the latest added group shows at the bottom, which is correct I guess.

Can anyone instruct me where to check and make the question/group order the same as mysql?

I have sometimes same issue with mysql. But a lot of bug was reported about this order :
bugs.limesurvey.org/view.php?id=13909
bugs.limesurvey.org/view.php?id=13729
bugs.limesurvey.org/view.php?id=13677
bugs.limesurvey.org/view.php?id=13851

Thank you Denis.
I follow the proposal in bugs.limesurvey.org/view.php?id=13677 to strip "|| 999999" part, and then delete tmp/assets/*, but still see incorrect order. :(
Is there a plan which release will have this fix?
Will fix solution be stated in the bug report?

Please update to the latest version. A lot of bugs has been fixed.

In case of problems, go to the question organizer and save the group order. Then clear the browser cache and reload the page.

Sure, I'll try. Thank you!

I've tried latest 3.14.0 , with no luck , bug #13677 is not fixed at this release.

Hi all,
I'm also having the problem with the order of the questions. I can see the correct order in "Reorder questions/questions groups" but the LS changes the order of 2 questions within one group.
I just update the LS to the version 3.14, but had no luck.
Thanks in advance for your help.

Hi,
I tried to activate the survey and got the error message ("Bad duplicate fieldname") about the 2 questions that were in the incorrect position. Tried to go back to the survey.
Now, panic, the survey has no questions anymore. Gone?
I do not know what to do.
Greetings,
Maria

Hi, again.
Sorry for the many posts.
I was able to import a backup. The questions are in the right position. I just lost an hour or so of work. But I'll move on from that backup.
Disregard my posts.
Have a nice day,
Maria

Please update old version to latest version.
