A volte può capitare che nel menu Componenti scompaia la voce Aggiornamenti di Joomla! . Questo di solito accade dopo un aggiornamento fatto copiando i nuovi file sul server.
Per ovviare a questo inconveniente e necessario andare a modificare una specifica tabella del database, solitamente tutti gli hosting mettono a disposizione il comodo strumento phpMyAdmin. La tabella da modificare è #__menu con la query seguente:
INSERT INTO `#__menu` (`menutype`, `title`, `alias`, `note`, `path`, `link`, `type`, `published`, `parent_id`, `level`, `component_id`, `checked_out`, `checked_out_time`, `browserNav`, `access`, `img`, `template_style_id`, `params`, `lft`, `rgt`, `home`, `language`, `client_id`)
VALUES ('menu', 'com_joomlaupdate', 'Joomla! Update', '', 'Joomla! Update', 'index.php?option=com_joomlaupdate', 'component', 0, 1, 1, (SELECT extension_id FROM #__extensions WHERE `name` = 'com_joomlaupdate'), 0, '0000-00-00 00:00:00', 0, 0, 'class:joomlaupdate', 0, '', 41, 42, 0, '*', 1);
