oAuth 2 - 404 when redirected back to forum
I signed up with Okta with intent of being my own authentication provider for several services.
Using Oauth2 SSO Plugin I set up the details provided to me by Okta.
Watching the network monitor in chrome I can see that all my connections to Okta OAuth Service seem OK. I get 302'd a couple times back to the forum, with a final url like myforum.com/index.php?p=/entry/oauth2&code=blabla
However, as I land back on my forum, and I can see from my okta account that the authentication was successful, my forum itself just says
HTTP Error communicating Code: 404
I can see that the 404 is to my forum itself, there's no 404 to any external service.
Not sure what's not configured right here..?
