After changing date format still getting error

[frank18]

...
I have made the changes to includes/languages/custom/english.php and also to admin/includes/languages/english.php
...

Did you make these changes:

 
  @setlocale(LC_TIME, 'en_AU.UTF-8'); 
  define('DATE_FORMAT_SHORT', '%d/%m/%Y');  // this is used for strftime() 
  define('DATE_FORMAT_LONG', '%A %d %B %Y'); // this is used for strftime() 
  define('DATE_FORMAT', 'd/m/Y'); // this is used for date() 
  define('DATE_TIME_FORMAT', DATE_FORMAT_SHORT . ' %H:%M:%S'); 
 
//// 
// Return date in raw format 
// $date should be in format mm/dd/yyyy 
// raw date is in format YYYYMMDD, or DDMMYYYY 
  if (!function_exists('zen_date_raw')) { 
    function zen_date_raw($date, $reverse = false) { 
      if ($reverse) { 
        return substr($date, 0, 2) . substr($date, 3, 2) . substr($date, 6, 4); 
      } else { 
        return substr($date, 6, 4) . substr($date, 3, 2) . substr($date, 0, 2); 
      } 
    } 
  } 

Above code reflects the settings in my (Aussie) stores.
