If you can’t see your font or if little squares are displayed instead of icons (because some icons are generated by a special font include in most themes), it probably means that your server is not allowed to load font files.

If this happens to you, pls contact you hosting service company and ask them to allow the loads of self hosted fonts on your servers.
