Alright, so I have been trying to solve this issue for a while. I am trying to achieve this link structure for the categories and posts on my website [www.MovieReserve.com] Movies: Action - http://www.moviereserve.com/movies/action/ Animation - http://www.moviereserve.com/movies/animation/ Comedy - http://www.moviereserve.com/movies/comedy/ Drama - http://www.moviereserve.com/movies/drama/ Fantasy - http://www.moviereserve.com/movies/fantasy/ Horror - http://www.moviereserve.com/movies/horror/ Romance - http://www.moviereserve.com/movies/romance/ Sci-Fi - http://www.moviereserve.com/movies/sci-fi/ Sports - http://www.moviereserve.com/movies/sports/ Suspense - http://www.moviereserve.com/movies/suspense/ Thriller - http://www.moviereserve.com/movies/thriller/ TV Shows: Action - http://www.moviereserve.com/tvshows/action/ Animation - http://www.moviereserve.com/tvshows/animation/ Comedy - http://www.moviereserve.com/tvshows/comedy/ Drama - http://www.moviereserve.com/tvshows/drama/ Fantasy - http://www.moviereserve.com/tvshows/fantasy/ Horror - http://www.moviereserve.com/tvshows/horror/ Romance - http://www.moviereserve.com/tvshows/romance/ Sci-Fi - http://www.moviereserve.com/tvshows/sci-fi/ Sports - http://www.moviereserve.com/tvshows/sports/ Suspense - http://www.moviereserve.com/tvshows/suspense/ Thriller - http://www.moviereserve.com/tvshows/thriller/ Code (markup): I could solve this by setting the link structure to /%category&/%postname% but that doesn't work perfectly as although I have 2 parent categories (Movies and TV Shows) with the other categories stemming from them, I can't assign the same slug to two different categories. I tried the Advanced Permalinks plugin, but that will only change the structure for posts and not the category itself. I tried the Custom Permalinks plugin, but that will only change the structure of the category and not for the posts within the category. I tried using both, but that makes both the category and the posts within them get an error (webpage not found for category and 404 for post).
unfortunately you will not be able to do what you are trying, because the values have to be unique, and for some odd reason the WP developer team decided that categories and tags will share the same table and thus you can't even have a tag and a category with the same slug. I suggest reversing the order of the links, first have the genre then the median. Personally I like it better that way.
