 * Hi folks,
 * This plugin gives me a warning in the admin that says:
    “The Database add-in 
   file db.php is not a W3 Total Cache drop-in. Remove it or disable Database Caching.[
   Remove for me]”
 * This warning is a false positive. It is reacting to a file db.php that was placed
   in the /wp-contents/ folder by a different plugin: Query Monitor. The db.php 
   file is necessary for that plugin to provide me with deep diagnostic info about
   database activity. W3 Total Cache should ignore this file and, frankly, should
   never interact with files in the root of /wp-contents/.

 * Thanks for noting this here. I was wondering what that error was about.
