404 error solution

Hi!
To fix 404 error I’ve made a fix in the custom_permalinks_original_post_link method. File custom-permalinks/frontend/class-custom-permalinks-frontend.php.

It works.

  public function custom_permalinks_original_post_link( $post_id ) {

    remove_filter( 'post_link', array( $this, 'custom_permalinks_post_link' ), 10, 3 );
    remove_filter( 'post_type_link', array( $this, 'custom_permalinks_post_link' ), 10, 2 );

    require_once ABSPATH . '/wp-admin/includes/post.php';
    list( $permalink, $post_name ) = get_sample_permalink( $post_id );

    // START FIX ERROR 404
    global $wpdb;
    $existing_post_name = $wpdb->get_var( "SELECT post_name FROM {$wpdb->posts} WHERE ID = " . ((int)$post_id ) );
    if( $existing_post_name )
      $post_name = $existing_post_name;
    // END FIX

    $permalink = str_replace( array( '%pagename%','%postname%' ), $post_name, $permalink );
    $permalink = ltrim( str_replace( home_url(), '', $permalink ), '/' );

    add_filter( 'post_link', array( $this, 'custom_permalinks_post_link' ), 10, 3 );
    add_filter( 'post_type_link', array( $this, 'custom_permalinks_post_link' ), 10, 2 );

    return $permalink;
  }
