title: File not writeable even though permissions are 777
body: <p>Something really weird is going on.</p>
  
  <p><code>httpd.conf</code> says apache runs as the apache user.</p>
  
  <p>I have chown-ed the files to be <code>apache:apache</code>.</p>
  
  <p>The file is still not writeable.</p>
  
  <p>I have set the permissions (of the entire webroot as a last resort) to be <code>777</code> and the file is still not writeable...</p>
  
  <p>The path is correct because <code>file_exists()</code> is <code>true</code> but <code>is_writeable</code> is <code>false</code>.</p>
  
  <p>Any ideas?</p>
