I found that code didn’t work, but that could be related to the version.
I’m currently running 4.0 and I fixed this issue by commenting out the following line in functions.php:
wp_enqueue_style( 'font-awesome-min' );
Just replace that line with:
//wp_enqueue_style( 'font-awesome-min' );
save the file and you’re good to go.
You may want to do the same to the line:
wp_enqueue_style( 'font-awesome-cdn' );
but that depends on what you’re after.
Hope that helps someone.
