My code for postmates tracking_url :
<iframe src="https://postmates.com/track/del_LtCu2--LzNXzjk" width="100%" height="450" frameborder="0" style="border:0" allowfullscreen ></iframe>
But it will give an error like this:
Refused to display 'https://postmates.com/track/del_LtCu2--LzNXzjk' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
I am using nginx on ubuntu 16.04.
