Error con un carrusel de productos

[comprarfacil]

Hola. he instalado un módulo que viene por defecto con el theme leo_sportshoes que se llama lofmanufcturescroll y me da el siguiente error:

 

Warning: Invalid argument supplied for foreach() in /usr/home/AhA4Ga6qfAws/comprarfacil.com/web/modules/lofmanufacturerscroll/lofmanufacturerscroll.php on line 303

 

en esa línea justo tengo lo siguiente:

 

$manufacturers = array();

foreach($id_manufacturers as $id_manufacturer){

$manufacturer = new Manufacturer($id_manufacturer,$cookie->id_lang);

if(Validate::isLoadedObject($manufacturer)){

$manufacturers[$id_manufacturer]['link'] = $link->getManufacturerLink($id_manufacturer,$manufacturer->link_rewrite,$cookie->id_lang);

$image_type = Configuration::get( $this->param_prefix.'_image_type' );

$id_images = (!file_exists(_PS_MANU_IMG_DIR_.'/'.$id_manufacturer.'-'.$image_type.'.jpg')) ? Language::getIsoById((int)$cookie->id_lang).'-default' : $id_manufacturer;

$manufacturers[$id_manufacturer]['linkIMG'] = _THEME_MANU_DIR_.$id_images.'-'.$image_type.'.jpg';

$manufacturers[$id_manufacturer]['id_manufacturer'] = $id_manufacturer;

$manufacturers[$id_manufacturer]['name'] = $manufacturer->name;

 

agradecería una ayuda porque me sale el warning en la parte de arriba de la web. Gracias
