My reply below was to a now-deleted post which contained the following. I’m still interested in FA5 icons myself…
Can we still add icons using this plugin?, asking because its not working anymore. I have to add Facebook, Twitter & Instagram. There is no option for SVG icon here: [screenshot]
Did it work for you before, what changed, and what have you tried?
Have you maybe downloaded the non-icon version of this plugin?
I was able to get Font Awesome 4 icons to work, but not Font Awesome 5 (except the 2-3 built-in ones): see my post above.
