Hi @Deflator0677, I have tested this and unfortunately I can not reproduce your issue. Is this something that happens sporadically or you can reproduce this issue constantly? Do you see some errors in the console (if you use chrome, go to More Tools -> Developer tools)?

I made a video to make it more understandable. I am able to reproduce each time. I use an instance from your free plan. @tibor.pacalat

There is no error in the web console.

I think it is because the question code is not unique anymore, and it is not forbid to save the question. A possible solution could be to change it to an available question number when the button "add a question" is pressed.

Thanks for the video, now it makes sense. This is a partial block since if you refresh the page, you can continue working on your survey.

Issues to be resolved:

1. The page should not freeze after a user tries to enter duplicate question code
2. When you click on "add question", the code provided should not be a duplicate of any already existing in the survey

We are waiting for a fix before switching to LimeSurvey. Do you have an idea when you planned to work on it?

@Deflator0677 it has been assigned so it should be tackled soon.
