Uncaught ReferenceError: Stripe is not defined

[qcaron]

Hi!

I get a javascript error Uncaught ReferenceError: Stripe is not defined for the following:

<script type="text/javascript">
    Stripe.setPublishableKey('pk_test_XXX');
</script>

which seems generated from this tag in the checkout.html template:

{% zebra_head_and_stripe_key %}

Did I miss including Stripe.js at some point??

Cheers, Quentin
