Hi,
I've looked again, and I saw that on top of updating the plugin php file, you also have to update the file components/com_hikashop/views/checkout/tmpl/step.php with the one from front/views/checkout/tmpl/step.php
but that's only useful with the old checkout of HikaShop and you said that you're not using the legacy checkout.
So I don't see why that wouldn't help, unless the issue you have is not the same as the issue @jazzmang had.
Normally, with the new GA plugin file, you should have the script below added to the HTML of each of the checkout pages:
<script type="text/javascript">
window.hikashop.ready(function(){
if(!ga || typeof(ga) != "function")
return;
ga(function(tracker){
var clientId = tracker.get("clientId"),
elem = document.getElementById("hikashop_checkout_analytics_field_ga");
if(elem) elem.value = clientId;
});
});
</script>
do you see it ?
