title: Blogger section doesn't appear on the layout page
body: <p>There is a problem about the layout page that is in Blogger Dashboard. I can see main and sidebar section on the layout page, but page-sidebar does not appear. Why is it happening?</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;b:if cond='data:blog.pageType in {&amp;quot;static_page&amp;quot;}'&gt;
      &lt;div class='col-sm-3 page-sidebar-area'&gt;
            &lt;b:section id='page-sidebar'/&gt;
      &lt;/div&gt;
  &lt;/b:if&gt;
  
  &lt;div class="col-sm-9"&gt;
      &lt;b:section id="main"&gt;..&lt;/b:section&gt;
  &lt;/div&gt;
  
  &lt;b:if cond='data:blog.pageType in {&amp;quot;index&amp;quot;,&amp;quot;item&amp;quot;}'&gt;&lt;/b:if&gt;
      &lt;div class='col-sm-3 sidebar-area'&gt;
          &lt;b:section id='sidebar'&gt;..&lt;/b:section&gt;
      &lt;/div&gt;
  &lt;/b:if&gt;
  </code></pre>
