[Plugin: My Post Order] Only shows a max of 10 posts in the loop

Replace showposts with posts_per_page.

Hey! Is not working with posts_per_page, it shows only 10 posts:

My query:
query_posts("posts_per_page=-1&section_name=Name")

I have the same problem.
Anyone have some idea??

I’m extremly sorry for late reply.

It is a bug.
For now, replace one function from includes/functions.php file with this one

function mpo_change_limit( $limit ) {
    global $paged, $myOffset, $wp_query;
    $section_name = isset($wp_query->query_vars['section_name']) ? $wp_query->query_vars['section_name'] : '';
    if ($section_name != '' ) {
      if (empty($paged)) {
        $paged = 1;
      }
      $postperpage = isset($wp_query->query_vars['posts_per_page']) ? $wp_query->query_vars['posts_per_page'] : intval(get_option('posts_per_page'));
      $pgstrt = ((intval($paged) -1) * $postperpage) + $myOffset . ', ';
      $limit = 'LIMIT ' . $pgstrt . $postperpage;
    }
    return $limit;
  }

Hi, it seems like you forgot to add this fix in the plugin, you should probably also add this too in your next update:
$paged = isset($wp_query->query_vars['paged']) ? $wp_query->query_vars['paged'] : $paged;

So when paged is specified in the query, it’s used instead of the global paged.
