==================

Hello,

I have just updated our Limesurvey version (from 3.X to 5.X). I used ComfortUpdate.
Now there is an error that always appears at the end of each survey after clicking "Submit". 

The error shows: 

500: Internal Error
CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'question.language' in 'where clause'.

Nevertheless the answers are saved and the survey is set to Completed.
Does anyone know what is the reason for this? Would be really helpful  

Chris

set debug mode = 2 and post the whole error screen when possible

Hi bismark,

I added a PDF of the error screen in debug mode=2. Hope this could help.

And I just tried it with another webspace and the same LS version. No problems here. So seems to be something specific with our installation/surveys and not with the limesurvey version?


 

Does this happen only with a specific survey or with all surveys?

If it is just with a specific survey, it could have to do with the survey itself. Copy the survey and check if the problem persists.

No, it happens to all surveys on this installation.
Just tried to add a new survey - same problem...

I used ComfortUpdate.

If you paid for ComfortUpdate you can contact LimeSurvey support directly.

We used the free trial, because it was our first bigger update.
Is it still possible to contact the support?

For me it seems that the plugin pdfReport causes the problems. LS3 != LS5. database schema has changed. deactivate the plugin.

Not sure. Most of us here in the forum are volunteers (users helping users) and we have no insight into the internal processes of the Limesurvey GmbH.

But to be honest, I don't think that they are too overly enthusiastic do provide professional support to non-clients. Maybe they see you as a "pontential client" as a users of the free trial. You can always try.

Thank you all!
The problem seems to be caused by the plugin. When I deactivated that, it worked. Fortunately, there is already a newer version for this plugin that is compatible with LS 5.X. I was able to reinstall this version and we can now use the plugin & get no more error message  

Thanks a lot. And sorry if it was stupid questions - don't know much about codes and stuff...
