Hi,

I follow a official guide to set a FontAwesome icon for forum: https://invisioncommunity.com/4guides/themes-and-customizations/tips-tricks_362/changing-fontawesome-icons-per-forum-r164/

I add this code in custom.css:

/*Forum personalized icon from FontAwesome*/
[data-forumid="10"] .fa-comments:before {
content: "\f091";
}
[data-forumid="5"] .fa-comments:before {
content: "\f11b";
}
[data-forumid="9"] .fa-comments:before {
content: "\f6e2";
}
[data-forumid="6"] .fa-comments:before {
content: "\f059";
}
[data-forumid="11"] .fa-comments:before {
content: "\f1ea";
}
[data-forumid="2"] .fa-comments:before {
content: "\f52b";
}

But not all icons work properly, even if the code works, and the icons are part of the free icons.

Can anyone tell me why?

Your icons for forum id 2 and 9 are invalid. Keep in mind we are using FontAwesome 4.7, not v5.

Thanks for the reply!
I didn't think an old FontAwesome fusion was used. It would be nice to be updated!
Thanks again for the support.

Yes... yes it would...

I noticed I could only use icons that started with 'f0' 

All others did not work.
