 * Hi,
    I recently installed Wordfence, and have been getting an intermittent error:
 * > Notice: Undefined index: HTTP_REFERER in /home/(directory)/(site directory)/
   > wp-content/plugins/wordfence/lib/wfUtils.php on line 586
 * When I Google parts of this error (specifically “wfUtils.php on line 586” it 
   shows that Google’s bots are receiving the error on other pages, too. I’m running
   Chrome on Windows 7 at work and 8.1 at home, and I’ve seen it in IE and Firefox
   too. It seems to appear (and show my directories!) no matter who’s looking at
   the site.

 * EDIT: Sorry, yes I did have my WP_CONFIG File set to Debug “yes.” Still happening
   though.
