I'm having an issue with your Popularity Contest plugin, version 2.0b2, although it started happening even before that...
Basically, if I use the provided widget or use any of the PHP code other than "akpc_most_popular()" (for example for categories or time periods), the list of popular posts displays "(none)", even though in the backend all of the popular posts are displayed correctly. If I use the PHP code akpc_most_popular() however, it displays properly.
This is very frustrating. Any idea what may be going on?
