XF 1.5 Issue with Time Zones

[Blackbeard]

I get this error in the Xenforo dashboard. Not sure why:

xception: DateTimeZone::__construct(): Unknown or bad timezone () - library/XenForo/ControllerPublic/Member.php:74

It could be due to an invalid timezone on a member profile, but that shouldn't be possible as the registration shouldn't save.

What is the actual URL to the site?
