title: jekyll pages work locally but not when online
body: <p>I am trying to add a couple links to my jekyll page. Here is the code I added to my _data/links.yml file (Home was there previously, I added the last two):</p>
  
  <pre><code>- url: /
    title: Home
  
  - url: /about
    title: About
  
  - url: /thoughts
    title: Thoughts
  </code></pre>
  
  <p>It works locally but not when I host my page on github pages.  I know jekyll versions are different, I have 2.0.3 locally and I'm not sure what version is on github pages. But this seems like a relatively simple thing. When I click on these links I get a 404 error.</p>
  
  <p>My page is here <a href="http://int-A.github.io" rel="nofollow">int-A.github.io</a> and code is hosted <a href="https://github.com/int-A" rel="nofollow">here</a>. Is there something that changed in version 2 of Jekyll that would allow this to work but not on an older version (which ever is on github pages)</p>
