Thanks for the reply jmangelo.You have a good point - since none of my “Allowed Callback URLs” have anything with an apostrophe in it.
I did run it on Chrome with the developer tools open on Network. As soon as I click OK on the Autg0 login screen, it redirects to http://localhost:60856/’ and if I look at the activity, I see two items:
signin-auth0 (Status: 203, Type: x-www-form-urlencoded, Initiator: codexcreations.eu.auth0.com/login/callback:1)
' (Status: 404, Type: document, initiator: signin-auth0)
Trying to figure it out… will let you know if I do. Thanks again…
