Boris\' answer to the above question seems to make sense, but I installed the Font Awesome files on my server and the problem remains:
I am having same issue, we use the fonts on router board using micro httpd. i added Access-Control-Allow-Origin: * header but not working for me.
i found in firebug that the woff file is not returing anything in response text. the same thing if i use CDN url, everything works fine. so on local micro-httpd server need some mandatory header to configure. please tell me also the exact mime types for all fonts needed.
