BUG controllers/ContactController.php (prestashop 1.4)

[tamu secreto]

File controllers/ContactController.php call has an error:

find line 204

if (isset($filename) AND rename($_FILES['fileUpload']['tmp_name'], _PS_MODULE_DIR_.'../upload/'.$filename))

I'm not sure possible solution:

if (isset($filename) AND rename($_FILES['fileUpload']['tmp_name'], _PS_ROOT_DIR_.'/upload/'.$filename))
