I've spent hours trying to get this to work, but the icons simply do not show up.
I don't know anything about coding PHP, and I know very little about WP itself, but I did manage to edit the four templates that were listed on the Template Tags page. I've double-checked those twice.
I tried the Lite version of the plugin and did get icons to appear in the Category list in the sidebar, but there was still no icon in front of the post title, which is the one I really want; and anyway, I want to use the full version because I want the option of more than one icon.
Theme: Suffusion (I'm actually using a child theme of Suffusion, but I've also tried going back to the main theme and there still were no icons)
Any tips welcome.
