title: Warning: require(/wp-includes/load.php) [function.require]: failed to open stream
body: <p>I uninstalled the W3 Total Cache plugin and added the WP Super Cache; however, the second plugin didn't get activated. I believe it was due to some W3 Total Cache files still showing on my blog and I went into FTP to remove them. Now I'm getting the below error message:</p>
  
  <pre><code>Warning: require(/wp-includes/load.php) [function.require]: failed to open 
  stream: No such file or directory in /wp-settings.php on line 21
  
  Fatal error: require() [function.require]: Failed opening required 
  '/wp-includes/load.php' in /wp-settings.php on line 21
