[Maczeta]

Hi,

My Prestashop 1.6 works Ok, www.mogio.eu -> debug on

but when I add Product and my product is added that I don't preview my product and I have errors:

Warning: Use of undefined constant _RIJNDAEL_KEY_ - assumed '_RIJNDAEL_KEY_' (this will throw an Error in a future version of PHP) in /home/mogioer/www/classes/Cookie.php on line 79
