@thymon sorry, can’t help… I would expand that > in the red box u posted and get the name of the icon specified and check against the library

@thymon can you move over the icons not shown and show their complete set of classes. There needs to be something like .fa.fas.fa-arrow

@lavolp3
I didn’t find .fa.fas.fa-arrow

I think that I found something.

How to force Font Awesome FREE ?

It works when Font Awesome 5 FREE are activated, not with FontAwesome.

[thymon]

OK I found it !! :)

.fa {
  font-family: "Font Awesome 5 Free";
  font-weight: 900;
  content: "\f007";
}

@thymon Great and sorry I haven’t answered. But I don’t really understand what’s going wrong there and why it is applying a font that you cannot use for free.
