Troubleshoot with the display of cart/order-detail

[Fabr]

Hello,

I'm using the version 1.6.0.9 with Deco Design 2.7.0 theme and the megaproduct module which perfectly fit for order with special measure and impact the price calculation.

When I want to display the order detail shopping cart, with some of my products (which are not managed by the megaproduct's module so for those which act as a "normal" product), I've got this notice message

Notice: Undefined offset: 2 in C:\wamp\www\prestashop\tools\smarty\sysplugins\smarty_internal_templatebase.php(157) : eval()'d code on line 109

it would be ok (i can modify the configuation to hide this) if there wasn't a "crash" on the display of the cart, without the possibility to proceed to check out

like this see attachment

 

 

My question is wich files (template controller) are used in the shopping cart summary. Does this error come from a controller because i've tried already to change shopping-cart.tpl and order-detail.tpl

 

Thank in advanced for yours answers,

Fabr
