In file template/default/bbpress-functions.php, line 218:
bbp_enqueue_script( $handle, $attributes[‘file’], $attributes[‘dependencies’], $this->version, ‘screen’ );
i think it should replace by this line :
bbp_enqueue_script( $handle, plugin_dir_url( __FILE__).$attributes[‘file’], $attributes[‘dependencies’], $this->version, ‘screen’ );
when using child-theme. I think it works not fine.
