title: Folder Permissions Error from WordPress on Localhost
body: <p>I am no longer able to auto-update my local WordPress install. The problem started after <a href="http://www.cnet.com/how-to/quickly-fix-dropbox-permissions-errors-in-os-x/" rel="nofollow noreferrer">fixing dropbox file permission errors</a>. Now when I try to install I get this message:</p>
  
  <pre><code>Downloading update from https://downloads.wordpress.org/release/wordpress-3.9.2-partial-1.zip…
  
  Unpacking the update…
  
  Could not create directory.
  
  Installation Failed
  </code></pre>
  
  <p><code>sudo chmod -R 755 myblog</code> gives same error. </p>
  
  <p><code>sudo chmod -R 757 myblog</code> works, but <a href="https://stackoverflow.com/questions/5651180/is-chmod-757-safe">757 is bad</a>.</p>
  
  <p>Why is it failing and is there a way to get it to work with 755?</p>
