Access-Control-Allow-Origin Wordpress/WPML/WP Google Maps

I'm getting the following errors on the console, when I switch between domains.

I understand the logic of why this is happening, but after reading around, I have zero idea how to fix this for XML files! Some assistance would be fantastic and greatly received!

GET http://ift.tt/1xyI5NT 
(index):1 XMLHttpRequest cannot load http://ift.tt/1xyI5NT. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://de.example.com' is therefore not allowed access. The response had HTTP status code 401.
