[v1.3.1] Cache missing & Admin setting/setting is BLANK

1. Edit /config.php change
define('DIR_CACHE', '/home/webpages/opencart/cache/');
to
define('DIR_CACHE', '/home/webpages/opencart/system/cache/');
solve my cache directory not found problem.

2. Login as admin go admin->configuration->setting (entire screen BLANK). Still checking.
PHP Fatal error: Call to undefined function timezone_identifiers_list() in /home/opencart/admin/controller/setting/setting.php on line 297
