Comment (by majhes):

 Please try using code below:

 add_filter( 'category_rewrite_rules', 'vipx_filter_category_rewrite_rules'
 );
 function vipx_filter_category_rewrite_rules( $rules ) {
     $categories = get_categories( array( 'hide_empty' => false ) );

     if ( is_array( $categories ) && ! empty( $categories ) ) {
         $slugs = array();
         foreach ( $categories as $category ) {
             if ( is_object( $category ) && ! is_wp_error( $category ) ) {
                 if ( 0 == $category->category_parent ) {
                     $slugs[] = $category->slug;
                 } else {
                     $slugs[] = trim( get_category_parents(
 $category->term_id, false, '/', true ), '/' );
                 }
             }
         }

         if ( ! empty( $slugs ) ) {
             $rules = array();

             foreach ( $slugs as $slug ) {
                 $rules[ '(' . $slug .
 ')/feed/(feed|rdf|rss|rss2|atom)?/?$' ] =
 'index.php?category_name=$matches[1]&feed=$matches[2]';
                 $rules[ '(' . $slug . ')/(feed|rdf|rss|rss2|atom)/?$' ] =
 'index.php?category_name=$matches[1]&feed=$matches[2]';
                 $rules[ '(' . $slug . ')(/page/(\d+)/?)?$' ] =
 'index.php?category_name=$matches[1]&paged=$matches[3]';
             }
         }
     }
     return $rules;
 }

 IMPORTANT EDIT: There was a bug in pagination, pages 10+ didn't work
 properly.
 Now fixed: (\d)+ changed to (\d+) .

 Hope this will be helpful :)
