No worries, it's not urgent ?
I'm unfamiliar with redirect url whitelisting, could you explain this bit? Do I also need to set anything special once I make the Discord App? I just revealed the secret, copied that and copied the client ID. It's also worth pointing out this is the first time I've set anything that uses alternative logins, is there something else I might be missing? I didn't see anything in the IPS docs.

I also get this, which I assume is broken, in the admin area of Login and Registration > Discord
Hope it helps!
