Slight error I found in Templates > Core > Front > Global > userBar this:
<i class="fa xfa-users" aria-hidden="true"></i>
Needs to be:
<i class="fa fa-users" aria-hidden="true"></i>
Other wise the icon does not show.
Font awesome's not working on the nav menu for some reason. I enabled it and this is what shows instead of the icons. I have tried re-installing twice now.
