/** DateTime::diff issues
  * SEEMS THERE IS AN ISSUE WITH PHP >= 5.3.0
  * SO I DECIDED TO CREATE AN ALTERNATE FUNCTION TO SOLVE IT, TO ENABLE THIS FUNCTION:
  * REPLACE:
      $datetime1 = new DateTime(date('Y-m-d h:i:s'));
      $datetime2 = new DateTime($UpgradeExpire);
      $interval = $datetime1->diff($datetime2);
      $UpgDays = $interval->format('%R%a');
  * WITH:
      $UpgDays = date_diff(date('Y-m-d h:i:s'), $UpgradeExpire);
  * ENABLE THIS FUNCTION:
    function date_diff($date1, $date2) {
      $current = $date1;
      $datetime2 = date_create($date2);
      $count = 0;

        $count++;
      }
