In inc/html.php :
459 $summary = $revinfo['sum'];
460 if($revinfo['user']) {
461 $editor = $revinfo['user'];
462 } else {
463 $editor = $revinfo['ip'];
464 }
465 $sizechange = $revinfo['sizechange'];
At first, I tried with $event->data->_content['revinfo']['ip'] , but it didn't work well.
Then I tried with $event->data->_content['revinfo']['ip'] , but it still doesn't work.
