I'm using Frusterick Manners
As far as I can see, in Frusterick Manners the icons are PNG-Files which are included via CSS. That means between Frusterick Manners and Greebo the including of the icons has changed completely.
From which version did you take the files with which you restored your template - maybe Greebo? Have you ever done the same restoration before you did it because I advised you to?
