Im currently facing a strange Issue on my Wordpress and Discourse Installation.
I’ve setup Wordpress as SSO Provider for Discourse since 2018.
So far everything worked fine. Since recent I get the Error “Invalid Request” , when a User is accessing the Forum on the Sub Url “discourse.sub.domain.com” directly, gets redirected to the Wordpress Login Page “sub.domain.com/login” and logs in:
When the User access the Forum URL again “discourse.sub.domain.com” he’s logged in and everything works fine.
I’ve renewed the SSO Secrets and they seem to work fine, the User Login works. I also did renew the API Key and that one also works:
I’ve activated the Debug on Wordpress and Discourse, but no error gets logged inside it:
Does the Wordpress SSO Plugin have any other debugg login option to check?
