title: Wordpress page suddenly blank
body: <p>I have a WordPress website that's been running for almost two years now. All of a sudden, it started to show a blank page on any public page. The admin part on <code>/wp-admin</code> is still working without any problems.</p>
  
  <p>A http request is successful (status 200), but the returned content is completely empty (not even an  tag).</p>
  
  <p>I'm not really a PHP/WP expert. A simple web search got a lot of results, but mostly old stuff and never any clear conclusion of the problem's source, i.e. how to fix it. I already enabled <code>WP_DEBUG</code> in wp-config.php, but this only shows debug messages in wp-admin, but the public page remains blank.</p>
  
  <p>Where should I continue searching?</p>
  
  <p>The problematic website is <a href="http://lolkitten.org/" rel="nofollow">http://lolkitten.org/</a>.</p>
  
  <p><strong>Update</strong></p>
  
  <p>I just found <code>index.php</code> inside my <code>public_html</code>, which was empty. After writing something into it, it appears on my home page! Also, there's a directory <code>/home/&lt;user&gt;/home/&lt;user&gt;/public_html/</code> which looks like complete nonsense to me.</p>
  
  <p><strong>Update 2</strong></p>
  
  <p>The Problem solved itself after upgrading to Wordpress 3.8. I don't know why, but it seems like some files (like index.php) were messed up and got replaced by fresh ones in this update.</p>
  
  <p><strong>Possible solution / workaround</strong></p>
  
  <p>I've had this problem again. This time, my <code>index.php</code> was completely empty. In my dashboard, under <em>Dashboard > Updates</em>, I clicked on <em>Re-install Now</em> and it fixed itself.</p>
