Hey,
I googled a bit for solutions to this problem. I Added an adviced link within the body element and also font-weight: 900; to the css.
All it shows though, as you see - is the gift icon in the middle but the others appears with error “marks”.
How come this happens??
Not sure why but it doesn’t seem to be working with the js version of font-awesome.
Remove the script and then add font-awesome to the CSS in the Settings (Settings > CSS > type in font-awesome in the search box > click the link to add the CSS file)
Hurray 
that worked!
Thanks!
