Built-in icons are gone – "Access error"?

[spooksweden]

I noticed that the search icon and the icons in the address widget have disappeared – When I start up the console I can see the following message:

Access to Font at 'http://lodoninfra.se/wp-content/themes/unicon/framework/css/font/icomoon.ttf' from origin 'http://www.lodoninfra.se' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.lodoninfra.se' is therefore not allowed access.

Any ideas on how to solve this?
Thanks!!
Best, Thomas
