I can’t seem to replicate the issue on my end. Even when I check the demo – http://demo.appfinite.com/epik/ it doesn’t show up….so I’m not exactly sure why that is there.
I did a search on StudioPress to see if anyone had a similar issue, and one user suggested it could be the fact that there was a post without a title. So check and make sure the permalink/post that is showing up has a title and see if that fixes it.
Here is the thread I got this info from – http://www.studiopress.com/forums/topic/how-to-remove-permalinks/
