Need help with a client updates

⚠ Template Override Token protection

The following template override files appear to be missing token protection. Update these files manually.
Note: You may not find a place to insert the missing code if your overrides differ significantly from the original files, and you may not need to add it at all.

In the following file(s), append &<?php echo JSession::getFormToken(); ?>=1 to the hardcoded order-placement AJAX query string:

data: 'option=com_j2store&view=checkout&task=confirm&<?php echo JSession::getFormToken(); ?>=1'

• templates/bella_pro/html/com_j2store/checkout/default.php

In the following file(s), add JSession::getFormToken() => '1' to the getCartUrl function.

$platform->getCartUrl(array(JSession::getFormToken() => '1', ...

• templates/bella_pro/html/com_j2store/carts/default.php
• templates/bella_pro/html/com_j2store/carts/default_items.php
• templates/bella_pro/html/mod_j2store_cart/detailcartonhover.php

In the following file(s), add data-<?php echo JSession::getFormToken(); ?>="1" as an attribute on the link with class j2store_add_to_cart_button:

<a class="... j2store_add_to_cart_button" data-<?php echo JSession::getFormToken(); ?>="1">...</a>

• templates/bella_pro/html/com_j2store/templates/uikit3/cart.php

After updating, clear the Joomla cache, if enabled.

Thank you Oliver

I still has an issue if there is somthing in the cart you want to delete you get this 

The most recent request was denied because it had an invalid security token. Please refresh the page and try again.

$product = $this->singleton_product;
$params = $this->singleton_params;
$action = 'index.php?option=com_j2store&view=carts&task=addItem&product_id='.$product->j2store_product_id;
?>
<?php echo J2Store::plugin()->eventWithHtml('BeforeAddToCartButton', array($product, J2Store::utilities()->getContext('cart'))); ?>
<div class="cart-action-complete" style="display:none;">
<p class="text-success">
<?php echo JText::_('J2STORE_ITEM_ADDED_TO_CART');?>
