Editing a survey question in Creation mode returns an error

Hi,

 

Trying to edit a question when a survey is in creation mode returns the standard message “Your session might have expired…”.

In validation mode, it is ok. However, according to the documentation, the modifications of the structure should be done when the survey is in Creation mode.

Editing an answer is ok.

 

Is it a bug?

 

Regards,

Yannick
