I tried to add a few FA5 icons to a page edited with the standard WP editor by searching the fontawesome page and pasting in the HTML. When I preview or save and view the page, the icons do not render. I am testing this using the latest version of Pro. On my other X powered site I have done the same thing without an issue. The Pro site is fairly barebones. I do have Ubermenu running on my X site that FA5 works on. So perhaps Uber menu is loading its call for FA5.
In order to add FA5 icons outside of the builders, do we need to do anything special?
