It did not work for some reason. I am out of ideas at the moment, I don’t get why the same exact configuration yields a different output. It must be some sort of a conflict, which does not happen on the other environment, but I can’t se how is that possible.
I cross checked the source code, traced it back completely, and everything seems to be okay, it should work as on the development site.
Anyways, if you can somehow allow access to the live after a backup let me know, and I will try to get to the bottom of this. I am 99% sure this is something very minor. Probably a piece of code conflicts somewhere with another piece of code which is very specific for that environment.
If you switch back to the “Classic” script loading, that will resolve the issue, I can see the events firing with that loading method.
