rewrite = true causing 404 to custom post types [closed]

Question

I am trying to create a custom post type for "Blogs". When I change rewrite to true I get 404 to the custom post type.

This is my custom post type code:

<?
  add_action('init', 'kula_custom_post_blog_posts_init');
  function kula_custom_post_blog_posts_init() 
  {
    $labels = array(
      'name' => 'Blogs',
      'singular_name' => 'Blog'
    );

    $args = array(
      'labels' => $labels,
      'public' => true,
      'publicly_queryable' => true,
      'show_ui' => true, 
      'show_in_menu' => true, 
      'query_var' => true,
      'rewrite' => true,
      'capability_type' => 'post',
      'has_archive' => true, 
      'hierarchical' => false,
      'menu_position' => null,
      'supports' => array('title','editor','author','thumbnail','excerpt','comments')
    ); 
    register_post_type('blog-post',$args);
  }
?>

That's practically copied right out of Codex. So I don't think that's the problem. I also checked my .htaccess file and it has all the right code:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

What else might be causing the problem?

Thanks
