Ensure that the redirect / callback URL in your WordPress plugin settings matches the one set in Keycloak's client settings. |
| I am encountering an "We are sorry, page not found" error. How can I resolve this ? | Keycloak has made changes to its endpoints starting from version 18. Consequently, it is no longer required to include the "/auth" substring in the endpoints when connecting to your Keycloak Provider. Therefore, I kindly request that you update the endpoints in our OAuth Client plugin to ensure compatibility with the latest version of Keycloak by looking at our guide. |
