 * I’ve never had an issue with DB Cache Reloaded before. But since upgrading to
   the latest version, it doesn’t play nicely with WordPress. I keep getting: “wpdb
   class is redefined, plugin cannot work! Previous definition is at E:\inetpub\
   vhosts\northcoasttec.com\httpdocs\wp-includes\wp-db.php:52.” I’ve followed the
   instructions and disabled the cache, saved, then re-enabled and saved again. 
   As soon as I navigate to another page, the error appears at the top of the page
   again.
 * You have a link on the top of the page: “please check FAQ how to do manual upgrade.”
   I don’t see anything on that page that refers to manually upgrading the plugin.
   Please help! Thanks for a great plugin.
