[lolalola]

With prestashop 1.3 everything work fine, but when insert in Prestashop 1.4 this module do not see in admin panel.
Why? Whats change with modules in Prestashop 1.4?

Thanks

<?php
class Fashion extends Module
{
   function __construct()
   {
       $this->name = 'fashion';
       $this->tab = 'front_office_features';
       $this->version = 1.0;

       parent::__construct();

       $this->page = basename(__FILE__, '.php');
       $this->displayName = $this->l('Block Fashion');
       $this->description = $this->l('Add a fashion block');
   }

   function install()
   {
       if (!parent::install())
           return false;

       if(!$this->registerHook('leftColumn'))
           return false;

       return true;
   }

   function hookLeftColumn($params)
   {
       return $this->display(__FILE__, 'fashion.tpl');
   }
}
?>

You need an XML file now inside the module folder called config.xml which has simillar settings but is how PrestaShop 1.4 loads the information (They've used XSLT instead of php for rendering I think to cut load time).

But i have read, this isn't required. This is not true?

It fixed my problem, unless there was something wrong with your original code.

Unfortuneatly, for me my presta does not read config.xml files. Info in my xml is different than in module, and PS shows one from class properties not xml. Any reason why? (would be cool if module page loaded faster)
