Resource interpreted as Stylesheet but transferred with MIME type text/plain

I am getting the following message in browser console using the Preview.

Resource interpreted as Stylesheet but transferred with MIME type text/plain: "http://192.168.56.1:57906/bootstrap/css/bootstrap.min.css".

This doesn't seem to be a problem for Chrome/FF but IE doesn't render the site in Preview. I've sat on this for a little while but thought I'd bring it up now.
