I get the same message from the in game link, the forum link, and even when I go through google. It tells me:
Unexpected non-MediaWiki exception encountered, of type "Exception"
exception 'Exception' with message 'DateTimeZone::__construct() [<a href='datetimezone.--construct'>datetimezone.--construct</a>]: Unknown or bad timezone (GMT)' in /www/gp_en/includes/GlobalFunctions.php:2081

Maybe it doesn't like the time zone here in Hawaii. This has been going on for over 12 hours. First time I have experienced any difficulty.
