Font Awesome Icons not showing

Let me start with that I know near nothing about coding…I have solved every problem thus far through forums and trial and error, but I am now stumped.

My site https://www.glidemobility.com was working properly until yesterday, when all of the Font Awesome icons stopped displaying. I don’t remember changing anything major yesterday, which is why I am so confused. I used the West theme (child) and Live Composer to build the site. Any help is appreciated.

Thanks!
