Uncaught incorrect header check or script not responding

first, sorry for my english.

I've tried many version of Unity with WebGl and it seems the bug with the relase always gives "incorrect header check" and with the development build, gives me some "script not responding"

tried with 5.3.4p2, 5.4.0b13 and 5.4.0b14

@EParent do you have a bug report # to share?

So sorry, just made a new build and now is functional with 5.4.0b14
