Font Awesome worked fine when I had index.html at the root with a link to font-awesome.css
<link rel="stylesheet" href="assets/plugins/font-awesome/css/font-awesome.css">
I changed the structure of my website for having multiple languages and I now have a folder called /en for all the pages in English and a folder called /de for all pages in German. I hence have /en/index.html
When I write in the head of index.html following:
<link rel="stylesheet" href="../assets/plugins/font-awesome/css/font-awesome.css">
then I get small boxes with numbers, like f086 instead of the icon comments for example. It means, the font-awesome.css file is found but the icons do not appear.
I tried to put the folder font-awesome in en/test/ and wrote in /en/index.html:
<link rel="stylesheet" href="test/font-awesome/css/font-awesome.css">
and it works again.
Are there some restrictions in the path of the css file font-awesome.css? Is it possible to change them or are there other ways of solving that problem?
