title: Adding number of posts to custom post archive page.
body: <p>I am using Wordpress and the Roots Template.
  I have created an archive page to show member profiles. - its just index.php saved out as archive-members.php so it gets the member posts, but I don't know how to change the number it displays. I want it to display all. 
  its not using any custom post type query, its just an archive of this post-type slug </p>
  
  <p>Here is my page code. </p>
  
  <pre><code>    &lt;div class="purple row"&gt;
    &lt;div class="container"&gt;
      &lt;div class="col-lg-12"&gt;
        &lt;?php get_template_part('templates/page', 'header'); ?&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  
  &lt;?php if (!have_posts()) : ?&gt;
    &lt;div class="alert alert-warning"&gt;
      &lt;?php _e('Sorry, no results were found.', 'roots'); ?&gt;
    &lt;/div&gt;
    &lt;?php get_search_form(); ?&gt;
  &lt;?php endif; ?&gt;
  
  &lt;div class="row pagecontent"&gt;
    &lt;div class="container"&gt;
      &lt;?php while (have_posts()) : the_post(); ?&gt;
      &lt;div class="col-sm-3"&gt;
        &lt;?php get_template_part('templates/members', get_post_format()); ?&gt;
      &lt;/div&gt;
  
    &lt;?php endwhile; ?&gt;
  
    &lt;?php if ($wp_query-&gt;max_num_pages &gt; 1) : ?&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  
    &lt;div class="container"&gt;
      &lt;div class="col-lg-12"&gt;
         &lt;nav class="post-nav"&gt;
      &lt;ul class="pager"&gt;
        &lt;li class="next"&gt;&lt;?php next_posts_link(__('Next Page &amp;rarr;', 'roots')); ?&gt;&lt;/li&gt;
        &lt;li class="previous"&gt;&lt;?php previous_posts_link(__('&amp;larr; Previous Page', 'roots')); ?&gt;&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/nav&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  
  
  &lt;?php endif; ?&gt;
  </code></pre>
