Showing 3 columns in categories

Hi,

i love your plugin but it doesnt work correct for my category page. I put your shortcode

<?php
$cat = get_category( get_query_var( 'cat' ) );
$category = $cat->slug;
echo do_shortcode('[ajax_load_more category="'.$category.'"]');
?>

in my archive.php file (I’am using Pinnacle theme). My categories look usually like the following 3 columns:

First Picture

With your shortcode it looks like:

Second Picture

Where I have to put the shortcode in the archive.php to get my 3 columns back? Here the code for the archive.php:

<?php get_header();

    get_template_part('templates/page', 'header');

      global $pinnacle, $postcolumn;
      if(pinnacle_display_sidebar()) {
        $display_sidebar = true;
        $fullclass = '';
      } else {$display_sidebar = false;
        $fullclass = 'fullwidth';
      }
      if(isset($pinnacle['category_post_summary']) && $pinnacle['category_post_summary'] == 'full'){
        $summary = 'full'; $postclass = "single-article fullpost";
      } else if(isset($pinnacle['category_post_summary']) && $pinnacle['category_post_summary'] == 'grid'){
          if(isset($pinnacle['category_post_grid_columns'])) {
            $blog_grid_column = $pinnacle['category_post_grid_columns'];
          } else {
            $blog_grid_column = '3';

            </div><!-- /.row-->
          </div><!-- /.content -->
    </div><!-- /.wrap -->
    <?php get_footer(); ?>

It would be nice to get an answer because I am loving it and I would like to use it in the long run.

Thanks and best regards
