CSS Files showing up with type text/plain

Question

I am attempting to serve my static blog (powered by jekyll) on my Ubuntu server but the CSS does not apply and I keep getting the issue:

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

In the source code, however, I explicitly list that these files are "text/css". Any ideas on how to solve this?

Answer 1

This was an Nginx issue. I needed to place

include /etc/nginx/mime.types;

in the "location /" block.
