    I just noticed my apache error log filled with PHP warnings regarding:

    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, cannot access protected method WP_Spider_Cache_Output::status_header()

    I noticed the status_header declaration is:

    protected function status_header( $status_header, $status_code = 200 )

    But it’s also being used as a filter in WP_Spider_Cache_Output::start()
