==================
We've migrated from LS 3.x to 6.4.2 and we got a fatal error when creating a new survey and using the "Copy" feature.

I've then upgrade from 6.4.2 to 6.5.1 and the error remains on page `/index.php/surveyAdministration/copy`

I'm running on PHP 8.1.27.  As far I understand, the problem comes from the codebase; using an invalid datatype when calling a function.





I found `"POST /index.php/surveyAdministration/copy HTTP/1.1" 500 7184` in my access log but nothing in the /etc/logs/error_log file; sorry.

Some follow up questions:

1. Can you create or import a survey?

2. What happens if you export and then import this survey or a different survey?

3. Can you break it down to certain surveys only?

4. Can you provide your problematic survey as LSS file for testing?

First of all, my apologies to have forgot to answer.

I can create a new survey and also duplicate another one. The problem was only by duplicating a given one.

The problem was discovered by my user i.e. someone in my company who create surveys. Since it was just a test on that moment, we agreed to not look further on this.

I think, for confidentiality reasons, I'm not allowed to export the survey and share it so, right now and until the user will ask to be able to clone that specific survey, I'm going to leave things as they are.

Perhaps the bug / problem will disappear in a next release of LimeSurvey.

Thanks Marcel for your answer.
