Error experiment logger + no response to sliders on pilot

URL of experiment:

Good afternoon,

I have two problems with the experiment I am performing for my PhD.

I created my experiment on PsychoPy builder. It works well and now I try to put it online but I have troubles.
The first problem is that I have the following error message when I start the pilot and the run: TypeError: psychoJS.experimentLogger is undefined. I looked for it on the forum but I didn’t find anything.
The second problem is that I can not respond to sliders when I do the pilot. I click on the response bar but nothing changes. However, I can respond when I do the run. I don’t understand why. If you have any ideas it would be really helpful.

Thank you very much for your help.
Best regards,

Alexis Vancappel
