Hi, I had the same issue, and your posts were very helpful. The issue is related to the using of SEO urls.

The solution that worked for me was to change de SEO route for the cart.

This is what I did:
System > URL manager > cart

Edit from:
route=cart

to:
route=checkout/cart

Hope it works for you.

The problem is that the controller cart.php is searching either one of these paths:
$checkCart = strpos($_SERVER['HTTP_REFERER'], 'checkout/cart');
$checkCheckout = strpos($_SERVER['HTTP_REFERER'], 'checkout/checkout');

But when i click on my cart, the path is simply just 'cart' without the checkout before.

So my question is, what the difference is between
index.php/checkout/cart
AND
index.php/cart

Thanks in advance for your time and help!

I am getting closer to a solution.
I found out that the controller cart.php on line 418 has a condidion of the cart.
Either it will be redirected or it will be "module"

I am absolutely new to Arastta so i do not know what this means

I think that i have to activate a module or so, but i am not sure.

[UPDATE]
Now the console pops up with this information:
Resource interpreted as Document but transferred with MIME type application/json

I will google that and see if i cand find the problem.
