Ok that’s what I was thinking, so is it possible to host the page and put a localhost url ? I tried to put a virtualhost that I have created with wampserver (http://twitch.pubsub), but after completing the input, it throw an error and say that the URL must be with https. Do I have to put only localhost and the full path to the file ?
Hum, index.html sorry, I used work with php file so it’s a bad habit to say that.
I copy and paste perfectly, and I did it 3 times, but it doesn’t work. Maybe I have to try one more time 
Thank you so much for your help
