Pusher.ScriptReceivers[1] is not a function about echo HOT 5 CLOSED

I'm seeing this as well. Pusher notifications are still functioning properly, but it shows in my console on page load.

Edit: I believe I've actually figured this out on my end. I'd previously been using Pusher notifications without Echo, and had forgotten to remove the Pusher.js file from my Elixir/Gulp compilation. I'm assuming this caused it to load Pusher twice, as Echo was imported which required Pusher as well.

It is a realtime notification system but it needs to be autheticate or logged by admin panel.You can make it a realtime notification system by changing some coding.
