Bonjour,
Comment faire pour supprimer cet erreur qui apparait au niveau d'un menu ?
Notice: Undefined variable: this in C:\xampp\htdocs\arpeggio\libraries\cms\application\cms.php on line 434

Le code concerné :
/**
* Returns the application JMenu object.
*
* @param string $name The name of the application/client.
* @param array $options An optional associative array of configuration settings.
*
* @return JMenu|null
*
* @since 3.2
*/
public function getMenu($name = null, $options = array())
{
if (!isset($name))
{
$name = $this->getName();
}

// Inject this application object into the JMenu tree if one isn't already specified
if (!isset($options['app']))
{
$options['app'] = $this;
}

try
{
$menu = JMenu::getInstance($name, $options);
}
catch (Exception $e)
{
return;
}

return $menu;
