 * Hi,
    I immediately got the message:
 * Notice: Undefined index: query in /home/goviral/public_html/goviralnow.net/wp-
   content/plugins/wp-fast-cache/wp-fast-cache.php on line 583
 * and when I tried to save a page with the plugin activated, I was just given a
   page of errors but no published page.
 * I have deactivated it but would like to get it working.
 * The site is at: goviralnow.net
 * and I use both Linux and Apache server.
 * Thanks
