The error.php contains:
<?php
if (($this->error->code) == '404') {
header('Location: /404-error-page');
exit;
} else {
echo $this->error->code;
}
?>

The error is:
Fatal error: Cannot access protected property JException::$code in /home/wlsdev53/public_html/http://joomla-dev.com/templates/t3_blank/error.php on line 2

Could someone please point me in the right direction?

Thanks.
Bill S.
