Font-awesome: facebook, google and twitter icon not work

[macagoraga]

I have correctly load fontawesome and all icons work fine apart facebook, google and twitter.

This is example of icon fa-users that work fine:

and on the same page this is for facebook, as you can see the css for fa-facebook:before is correctly loaded, but icon is not visibile:

Any idea what can be?

Thanks

Hi!

Thanks for being part of the Font Awesome Community.

Please note that Font Awesome 5 requires a different syntax for brand icons

The proper markup for facebook is fab fa-facebook

Hope it helps
