Missing "Sprite" icons / buttons
I'm re-styling an old community here:
Recently upgraded to Vanilla 3.3
Somewhere in the redesign process, I lost the "Sprite" buttons or icons somehow, and even if I disable Custom CSS altogether I don't get them back.
I'm referring to, for example, the "favorite" icon and little gear you would otherwise see next to categories and discussions to edit them.
Any idea what went wrong? And how I can fix it?
