title: Jekyll not generating pages in subfolders
body: <p>I use GitHub Pages and created some pages in a sub folder. It seems to be not generating pages I created in sub folder. All other pages work fine. The directory structure is like this:</p>
  
  <pre><code>/
  /index.html
  /_config.yaml
  /_includes
  /_layouts
  /_posts
  /tag
  /tag/personal.html
  /tag/videos.html
  </code></pre>
  
  <p>The pages inside the <code>/tag</code> directory are not generated by Jekyll. Also, usually GitHub sends an email if Jekyll build fails, but did not, in this case. Also, if I do any other changes it works, so the build is apparently not failing.</p>
  
  <p>The <code>/tag/personal.html</code> is here:</p>
  
  <pre><code>---
  layout: default
  title: Tag-personal
  permalink: /tag/personal/index.html
  tagspec: personal
  ---
  &lt;div id="tagpage"&gt;
    &lt;h1&gt;Posts tagged personal&lt;/h1&gt;
  {% include tags.html %}
  &lt;/div&gt;
  </code></pre>
  
  <p>and <code>/_includes/tags.html</code> is here:</p>
  
  <pre><code>{% for tag in post.tags %}
    {% if tag == page.tagspec %}
      {% assign ispostviable = true %}
    {% endif %}
  {% endfor %}
  
    &lt;ul class="posts"&gt;
  {% for post in site.posts %}
    {% if ispostviable == true %}
      &lt;li&gt;&lt;a href="{{ post.url }}"&gt;&lt;/li&gt;
    {% endif %}
  {% endfor %}
    &lt;/ul&gt;
  </code></pre>
  
  <p>PS: I use GitHub Pages and have no access to a Jekyll instance at my development machine (Windows).</p>
