 * Hi,
 * My site got hacked and upon restoring, the following message showed up at the
   header section.
 * Warning: Use of undefined constant HTTP_USER_AGENT – assumed ‘HTTP_USER_AGENT’(
   this will throw an Error in a future version of PHP) in /home/yyy/xxxx.com/wp
   content/themes/flash/header.php on line 1
 * How to resolve this?
 * Regards,
    Meijer D.
