        test
    <?php endwhile; endif; ?>

<!-- series -->
<?php get_footer(); ?>

function tvshows_taxonomy() {
register_taxonomy('tv_categories', array('tv,episodes',),
array(
    'show_admin_column' => true, 
    'hierarchical' => true, 
    'rewrite' => array('slug' => get_option('tv-category')),)
);
}
add_action('init', 'tvshows_taxonomy', 0);

// Register Series
function series() {

    $labels = array(

Answer 1

Smith,

Your code is right nothing to change in it. Just go to backend admin section and click on Settings -> Permalinks After that select "Post Name" in radio buttons and click on Save Changes. Done.

Refresh your single page it will work.

I'm going to say your call to flush_rewrite_rules() did not actually run. To be sure, add a quick manual flush to eg functions.php :

/* Trigger on wp-admin or cron and whathaveyou */
add_action('admin_init', function() {
   flush_rewrite_rules();
});

Flushing on init on a live site will degrade performance, etc. But it's useful to sanity check your flushes.

Fixed, i included the register post type only for admin. THis was the problem
