This worked for me: Add the following lines to your web.config
<system.webServer> <staticContent> <remove fileExtension=".woff"/> <mimeMap fileExtension=".woff" mimeType="application/x-font-woff" /> </staticContent> </system.webServer>
You have to add these lines because by default Apache is not configured with .woff as a default MIME-type. Apache default MIME-type This holds for IIS as well. As Seb Duggan explains here:IIS default MIME, by default .woff files will not be served by the server.
