I just migrated Prestashop 1.4.6.2 to Prestashop 1.6.1.7, despite some issues, especially with picture and birthday required, which I solved I have one issue remaining.
The developer, unfortunately, has updated the default PrestaShop template which I finally could solve but it might mean that he/she has changed more "core" files that I do not know and you guessed it, this developer did not leave any documentation.
The issue:
On 1.4 when someone adds something to the shopping_cart, the trolley turns green by using the global.css file.
Both the 1.4 and 1.6.1.7 have the following #header_nav.green in the global.css
#header_nav.green {
background-image:url('../img/cart_green.png');
In 1.6.1.7 however, the global.css file is the same but in the source on 1.4 you can read:
<!-- Block user information module HEADER --> <div id="header_user"> <ul id="header_nav" class="green"> <li id="shopping_cart">
where on 1.6.1.7 <!-- Block user information module HEADER --> <div id="header_user" > <ul id="header_nav"> <li id="shopping_cart">
Where in the system is PrestaShop telling the shopping cart that something has been added for the trolley to turn GREEN.
Appreciate your help
