title: PHP - Fatal error: Cannot redeclare class Config in /path/to/Config.php on line 44
body: <p>This is a WordPress local installation that I am trying to work with. I have not written a single line of this code myself. I don't understand what this error means:</p>
  
  <pre><code>Fatal error: Cannot redeclare class Config in /Applications/XAMPP/xamppfiles/lib/php/Config.php on line 44
  </code></pre>
  
  <p>Line 44 reads as follows:</p>
  
  <pre><code>class Config {
  </code></pre>
  
  <p>My guess is that a <code>Config</code> class has either already been declared elsewhere, or that this file is being executed for the second time.</p>
