Comment (by imageac):

 After upgrading Wordpress to 3.4.1, I faced 404 error with 'paged'
 categories, but it was soon resolved with assistance available in
 ticket:21209.  I added following code to the theme's functions.php file.

 {{{
 function hc_init() {
 global $wp_rewrite;

 //add rewrite rule.
 add_rewrite_rule("author/([^/]+)/page/?([0-9]{1,})/?$",'index.php?author_name=$matches[1]&paged=$matches[2]','top');


 add_rewrite_rule("(.+?)/page/?([0-9]{1,})/?$",'index.php?category_name=$matches[1]&paged=$matches[2]','top');


 $wp_rewrite->flush_rules(false);
 }

 add_action('init','hc_init');
 }}}

 As I explained earlier that my above code was super fit, and had no
 problem related to permalink and/or custom post type before upgrade to
 3.4.1.


 My steps:

 1. Yes, I added code mentioned-above to the theme's functions.php file.
 2. Yes, flushed rewrite rules by visiting the Permalink Settings screen.
 3. Yes, I created a new product (Product 1).
 4. But, when I visited /products/product-1/. The post returns 404 error as
 tested it.

 Please help me to fix 404 error with custom post type.
