I installed this plugin and set it up with my id, secret and setup the call back urls properly. But when I try to login or register using the plugin, the process works fine, it redirects me to the social media site, I log in to the account, grant permission to the app, it asks me whether i already have an account or i need to create a new account and connect it to the site, everything works fine till here. But then, it takes me back to the same login page and upon checking the users list through the WordPress dashboard, I find that no new user has been created.
