Lets say SOCIAL_CONNECT_PLUGIN_URL returns https://<your domain>/wp-content/plugins/social-connect for you. So the path would then be https://<your domain>/wp-content/plugins/social-connect/liveid/callback.php

When you create your Windows Live application, ensure that the return address you provide on the site while creating the application is the same.

What version of the plugin are you using? Have you tried running the diagnostics provided with the plugin ver 0.3? Try and see if it points you to what might be wrong.

Also, can you pls ensure the return URL you have provided on the Application created in Windows live is the same as this url – SOCIAL_CONNECT_PLUGIN_URL . ‘/liveid/callback.php’ (whatever that returns for you).
