How to change http to https in Prestashop 1.6 add cart

I enabled SSL on my Prestashop 1.6:

Preferences > General > Enable SSL
Preferences > General > Enable SSL on all pages

In .htaccess I used a following code:

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

before

# ~~start~~ Do not remove this comment, Prestashop will keep automatically the code outside this comment when .htaccess will be generated again

Everything looks fine but in view page source of website still I see:

<a class="button ajax_add_to_cart_button btn btn-default" href="http://www.myeshop.com/cart?add=1&amp;id_product=9&amp;token=2db68311c3192a52b4eca5bc1b2c218f" rel="nofollow" title="Add to cart" data-id-product="9"> <span>Add to cart</span> </a>

A href link in Add to cart button directs to http instead https. Can you help me please? Regards Jan

Solution

You should look at the smarty template concerned and seeing if classes or controllers are not overridden.

at least you can correct it, with Javascript with something like :

$(document).ready(function()
{

   $('.ajax_add_to_cart_button').each(function() {
                var href = $(this).attr('href');
                href = href.replace('http:', 'https:');
                $(this).attr('href', href);
        });

 });

But it's only for test mode not in production due to security !!! please read this thread : Change all occurrences of "http" to "https" on a wordpress page
