Voucher not working on Cart when SSL is enabled

[fulminado]

Hello everyone :-)

I have a site where I transplant the cart block on the Left Column.

My problem is described below:

When I use a voucher, the voucher is visible on the cart. Then if I try to delete the voucher, it gets removed from the cart, BUT if I refresh the page or add another product, the voucher is visible again! That only happens when I enable SSL. I believe is something wrong with the ajax-cart.js but I am not able to track it...

I am using prestashop 1.5.4 with default theme.

 

Thanx for your help in advance!
