I created an SSO by changing the DNN V8 core Login.ascx control, and after I redirect to another page and have already logged in once, there's an object reference empty error, but it doesn't happen if I delete my cookies. Any idea why this might happen? I tried a few other answers I read on the forum to this exception, like changing the option for usernames to be emails, and looking at the module definitions table, but I'm confused because I can't even see where that code is being called. Does it happen behind the scenes in the OnUserAuthenticated(eventArgs); event call that's supplied by the var eventArgs = new UserAuthenticatedEventArgs(objUser, objUser.Username, UserLoginStatus.LOGIN_SUCCESS, "DNN")?
