[Solved] Fatal error during checkout (secure_key problem)

[maestros]

Hello,

I have a strage error during checkout.

After I press the 'I confirm my order' link then a "Fatal Error" appears.

This is the html source code that I see:

<!-- Center --> 
 
Fatal error

While trying to isolate the error I saw that the error is caused when the following statement is executed:

cashondelivery/validation.php:

$cashOnDelivery->validateOrder((int)($cart->id), _PS_OS_PREPARATION_, $total, $cashOnDelivery->displayName, NULL, array(), NULL, false,$customer->secure_key);

Can someone tell me please what is the use of the secure_key?

I isolated the problem. It is cause here:

/classes/PaymentModule.php (101)

            if ($secure_key !== false AND $secure_key != $cart->secure_key)
               die(Tools::displayError());

Please, any help is valuable!

OK I solved the issue. Based on this bug:
http://forge.prestashop.com/browse/PSCFI-1272

I deleted all my customers using the administration -> Customers and I registered again.
Now I can complete the order with success.

PS: I could delete my customers because I have no production data yet. Only dummy customer records.
