I not sure where this here is coming from:
...
<!--- Your global JavaScript code can go here -->
<script async charset="utf-8" src="https://cdn.embedly.com/widgets/platform.js"></script>
...
But I would like to get rid of it or maybe import it into my File System and staticly reference it.
I am using the Quark Open Publishing Theme. Is this related to this or is it Grav specific?
Maybe someone already did it and can help me.
