Hi @triixx
Instead of return $msg;, I believe you can use the wp_redirect() function instead like this:
// These are just for testing. You need to get the actual
// value based on the registration
$success = false;
$error_code = '1'
// if the registration failed
if( !$success ){
wp_redirect( 'http://example.com/register/?success=false&error=' . $error_code );
}`
I hope this helps 🙂
