Prestashop 1.6.1.1 empty cart after Guest checkout
<p>I enabled guest checkout but after checkout I get popup with message that my cart is empty! :-( Product allow buying by Guest, I've checked it out. I can't find place in prestachop code witch responsible for empty my cart. I supose it happen with JQuery and AJAX because message apears without page reloading. How to check for what is acctually happen with cart object using firebug or other debuging tool?</p>

<p>I created logger function and i'm trying to find out when cart becomes empty but it happens suddenly.</p>

<pre><code>controllers\front\OrderOpcController.php

    class OrderOpcControllerCore extends ParentOrderController
{
[...]
public function init()
        {
            parent::init();
    [...]

    LoggerClass::MyLogger($this-&gt;context-&gt;cart, __LINE__);
</code></pre>

<p>When I add my first product to cart then I get follwing output:</p>
