Font Awesome has awesome for me for quite a while. However, I noticed that recently there's been a bit of a change and I haven't been successful in adjusting. Specifically, the fa class has been deprecated, according to what I read on the fontawesome site. Now we are supposed to use fab for projects like mine. Unfortunately, fab won't load. fa will still load just fine, but not for all the icons, just some of the icons.
Please see here, upper right corner: https://circularsmc.nationbuilder.com/
Twitter and Facebook are using the old fa class and they are loading.
Instagram is not loading using the new fab class. I tried it again next to it using the old fa class, but that's not working, either. (both are there, right next to each other, for reference).
I'm a bit flummoxed. Any idea what I'm doing wrong? I checked the Support page but it doesn't look like this issue is there.
