Problem trying to store cookie in Codeigniter 4

Your expire is too short. Its gotta be expire in the future. Basically time() + 86500;
It's probably too late, and you figured it out but, maybe someone else stumbles in this problem, besides you...or me.
ex: setcookie('testes_cook', 'Cooking testes??', time() + 86500, '/', '', $secure); //$secure - true if https, false if http

You can see things I made with codeigniter here: itart.pro its not overly impressive as I have very little time to learn.
