We have changed from Glyphicons in the old Govintranet theme to the Font Awesome sets in the new Govintra theme. The migration process attempts to match up common icons between the two sets, but we cannot cover everything.
You should take a look in the following areas to choose new icons:
Wonderwall: edit the new award categories on your left-hand dashboard menu.
News updates: edit the news update types on your left-hand dashboard menu.
Specify missing icons from the official Font Awesome set. The Govintra theme comes with a choice of Regular, Solid, Thin, Brands and Duotone fonts.
See our guide on using Font Awesome.
