SCRIBUUUU!
(This is my first topic post, so I don't know how else to get the developer's attention.)
The plugin is great, but I can't get the get_referrer_category() code to work. I've read all over the place.
This topic seems to be closest to finding my solution: http://wordpress.org/support/topic/plugin-smarter-navigation-get_referrer_category?replies=4
...but for the life of me, I can't understand the answer! Where is the dummy.css reference located? Then again, when I put the get_referrer_category() into my code, it still doesn't work on posts with single categories, so...
What I am trying to achieve is to add the category to the top of each single post like "posttitle" does on the top of each category loop when you click on the link in the sidebar.
