title: Cakephp Upgrade from 1.3 to 2.1
body: <p>UPDATE: the question i asked doesn't quite cover how deep i went in doing this upgrade! If you stumble on this, i hope the answer i pushed is useful to you</p>
  
  <p>So, in an effort to get the "forum" plugin working, i've decided to upgrade cakephp from 1.3 to 2.1</p>
  
  <p>(This was because the forum plugin uses something called CakeDC utils, and they are already up to cakephp 2.0, and surprise surprise, the 2.3 version of forum isn't clear which utils it works with...)</p>
  
  <p>Ok, so I have run the cake upgrader magic thing, in accordance with the instructions found here:</p>
  
  <p><a href="http://book.cakephp.org/2.0/en/console-and-shells/upgrade-shell.html#upgrade-shell" rel="noreferrer">http://book.cakephp.org/2.0/en/console-and-shells/upgrade-shell.html#upgrade-shell</a></p>
  
  <p>And i ran the upgrader, and it said it did a bunch of things, and it looks like it <em>did</em> do a bunch of things.</p>
  
  <p>Now when i visit my site, it is down - no response at all. </p>
  
  <p>The error logs in apache read:</p>
  
  <blockquote>
    <p>[Thu Apr 05 02:58:04 2012] [error] [client 173.45.125.112] PHP Fatal error:  Can't find application core file. Please create /cake_install/app/config/core.php, and make sure it is readable by PHP. in /cake_install/cake/libs/configure.php on line 393</p>
  </blockquote>
  
  <p>The reason that file doesn't exist is that it was changed to a capital "C" Config in the upgrade. What am i missing?</p>
