Error when using with Authelia

[dacrudg]

Hi. I'm using this plugin to connect Wordpress to Authelia. Here is a screenshot of what values it wants. What do I set for Login Endpoint, Userinfo Endpoint, etc. ?

I think I may have the values correct. And got this after trying to login:

ERROR (invalid_client): Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). The request was determined to be using 'token_endpoint_auth_method' method 'client_secret_post', however the OAuth 2.0 client registration does not allow this method.
