Php 策略在本地工作，而不是使用laravel 6在线工作

我使用laravel6创建了一个网站，我将其作为waktinghir.ma在线托管，我已经应用了双按钮编辑和删除策略，在本地它工作正常，但在联机它不工作，我知道我由在本地或联机创建此文件的同一用户进行身份验证

AnnoncePolicy.php

class AnnoncePolicy
{
    use HandlesAuthorization;
    public function before($user, $ability) {

        if($user->is_admin) {
            return true;
        }
    }
    public function view(User $user, Annonce $annonce)
    {
        return true;
    }
    public function create(User $user)
    {
        return true;
    }
    public function update(User $user, Annonce $annonce)
    {
        return $user->id === $annonce->user_id;
    }
    public function delete(User $user, Annonce $annonce)
    {
        return $user->id === $annonce->user_id;
    }
}
