Auto-Login after Registration

Hello,

I want my new users to e automatically logged in after they register.
Right now, they are directed to the login screen.

I’ve created a theme-my-plugin-custom.php and placed in my plugins directory.

I followed the code in this:

It didn’t work for me.

I followed the code this:

This is what’s currently in my custom.php file:

<?php
function tml_new_user_registered( $user_id ) {
	wp_set_auth_cookie( $user_id, false, is_ssl() );
    wp_redirect( admin_url( 'profile.php' ) );
    exit;
}
add_action( 'tml_new_user_registered', 'tml_new_user_registered' );
?>

Not sure what else to do! Really like this plugin but want users not have to enter the same details twice.

Please help – thanks!
