How did you tried the plugin? Was the plugin active during the upgrade?

I juste want to update the plugin. I put all the files in the directory. But i have not desactivate the plugin before. I my database there is no table call ow.notifications_notification Can you send me a dump for this table ? I try to install a oxwall on my computer local in order to retrieve this table. Is a solution for desactivate a plugin when you don't have acces to admin panel ? via ftp ?

CREATE TABLE IF NOT EXISTS `ow_notifications_notification` (
  `id` int(11) NOT NULL auto_increment,
  `entityType` varchar(255) NOT NULL,
  `entityId` int(11) NOT NULL,
  `action` varchar(255) NOT NULL,
  `userId` int(11) NOT NULL,
  `pluginKey` varchar(255) NOT NULL,
  `timeStamp` int(11) NOT NULL,
  `viewed` int(11) NOT NULL default '0',
  `sent` tinyint(4) NOT NULL default '0',
  `active` tinyint(4) NOT NULL default '1',
  `data` text,
  PRIMARY KEY  (`id`),
  UNIQUE KEY `entityType` (`entityType`,`entityId`,`userId`),
  KEY `timeStamp` (`timeStamp`),
  KEY `userId` (`userId`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
