I’ve now spent hour trying to get Font Awesome icons in the service section of my website. I’ve been playing around with the classes and settings in the Service Settings section of my posts that are linked with the Service section of the site but I’ve yet to get any logos. The closest I’ve come to is a grey circle without anything inside.
Sorry for the delay.
If I understood you correctly you want to change Service icons? To make this you can change the icons in “Service posts”, under post you will see “Service settings”. But I must clarify, use prefix “icon” instead of “fa” using Awesome Font.
