Is this your index.php? If so try it by querying from your theme's functions.php
http://codex.wordpress.org/Pagination#Removing_query_posts_from_the_main_loop

function my_post_queries( $query ) {
  // not an admin page and is the main query
  if (!is_admin() && $query->is_main_query()){
    if(is_home()){
      $query->set('posts_per_page', 10);
      $query->set('post_type', 'post');
    }
  }
}
add_action( 'pre_get_posts', 'my_post_queries' );
