guide du dévellopeur

[pak38]

Bonjour
 
Je débute dans la création de module en suivant le guide du dévellopeur 1.6.
 
Le module que j'ai créé "mymodule" s'affiche bien mais le lien "Click me!" m'envoit sur une page erreur 404 ; j'ai, pourtant, bien suivi le guide, je ne comprends pas.
 
J'ai même vider le cache manuellement.
 
Voici ma classe mymodule.php :

<?php
if (!defined('_PS_VERSION_'))
  exit;
 
class MyModule extends Module
{
  public function __construct()
  {
    $this->name = 'mymodule';
    $this->tab = 'front_office_features';
    $this->version = '1.0.0';
    $this->author = 'moi';
    $this->need_instance = 0;
    $this->ps_versions_compliancy = array('min' => '1.6', 'max' => _PS_VERSION_); 
    $this->bootstrap = true;
 
    parent::__construct();
 
    $this->displayName = $this->l('My module');
    $this->description = $this->l('Description of my module.');
 
    $this->confirmUninstall = $this->l('Are you sure you want to uninstall?');
 
    if (!Configuration::get('MYMODULE_NAME'))      
      $this->warning = $this->l('No name provided');
  }
  
  public function install()
  {
    if (Shop::isFeatureActive())
      Shop::setContext(Shop::CONTEXT_ALL);
 
    if (!parent::install() ||
      !$this->registerHook('leftColumn') ||
      !$this->registerHook('header') ||
      !Configuration::updateValue('MYMODULE_NAME', 'my friend')
    )
      return false;
 
    return true;
  }
  
  public function uninstall()
  {
    if (!parent::uninstall() ||
      !Configuration::deleteByName('MYMODULE_NAME')
    )
      return false;
 
    return true;
  }
  
  public function getContent()
  {
      $output = null;
 
      if (Tools::isSubmit('submit'.$this->name))
      {
          $my_module_name = strval(Tools::getValue('MYMODULE_NAME'));
          if (!$my_module_name
            || empty($my_module_name)
            || !Validate::isGenericName($my_module_name))
              $output .= $this->displayError($this->l('Invalid Configuration value'));
          else
