Unable to filter customer/user by username when Add New Order manually

In chrome, View > Developer > Javascript console. Do you see errors listed?

Hi Mike,

This is the error:
Mixed Content: The page at ‘https://www.forwardvia.com/wp-admin/post-new.php?post_type=shop_order’ was loaded over HTTPS, but requested an insecure stylesheet ‘https://fonts.googleapis.com/css?family=Oswald’. This request has been blocked; the content must be served over HTTPS.

Don’t think that will be related.

No errors after trying to search?
