code when returning to the survey

[squarroz]

Hello!

2 participants called me because when the wanted to go back to the survey in order to continue it, they were asked for a code...

Is there an option checked somewhere I haven't seen? I had to "reset without deleting the data" in order to permit them to continue the survey.

This happened when I used and html template.

The project number is 416295

Thanks a lot if you have a piece of information related to that problem!
