Redirect not working, any workaround?

The redirect isnt working for me, so when i submit a new post with WP User Frontend im still on the same Page and not redirected to the newly created post.

At the Moment i avoid this, by adding this to my functions.php:

function custom_redirect( $url ) {
    global $post;

    return home_url();
}
add_filter( 'wpuf_after_post_redirect', 'custom_redirect' );

But this only sends me to the home page. Is there any code to redirect me to the newly created post?

Thank you guys.
