title: wordpress theme page not showing plugin gallery
body: <p>I am new to Wordpress. I am trying to build a theme from scratch. 
  I created the page.php which is the following:</p>
  
  <pre><code>&lt;?php
  /**
   * The template for displaying pages
   *
   * This is the template that displays all pages by default.
   * Please note that this is the WordPress construct of pages and that
   * other "pages" on your WordPress site will use a different template.
   *
   * @package nameofpackage
   */
  
  get_header(); ?&gt;
  
  
  
  &lt;?php get_footer(); ?&gt;
  </code></pre>
  
  <p>I also installed the NextGen plugin. 
  I created a new page, and use the "add Gallery" button of NextGen; i ended up with </p>
  
  <pre><code>[ngg src="galleries" ids="1" display="basic_thumbnail"]
  </code></pre>
  
  <p>inside the text section of the page (the visual section shows the plugin logo in a box).</p>
  
  <p>When i tried to preview the result i only get the header and the footer with nothing in the middle; the inspector shows no presence of the code related to the gallery.</p>
  
  <p>If i try the same thing with ThemeFifteen it works.</p>
  
  <p>So my question is: is there something i need to include in the function.php that allows my theme to include the output of the plugin in the page? thx</p>
