More info: I made perfect duplicate for my site on localhost to experiment. On localhost ajax page loader is working with multi-columns, but on real website it isn’t. Why? I don’t know!!!!

Okay, I resolved the problem by changing query_posts to

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
      $args = array(
        'tag' => $tags,
        'paged' => $paged,
        'posts_per_page' => 9
      );
      query_posts($args);
