I have been unable to resolve this. I downloaded icons and using the demo they all show up back when they should show up in a more colorful fashion
What they should look like: http://www.flaticon.com/packs/interaction-assets-2
How it looks like for me: http://chathelpdesk.com/pp-menu/demo/assets/fonts/flaticon.html
I see the outline of the icon, I am using the default CSS. The outline of the font icon is there. Could someone help figure out how to un-black the icons...
