[Mediawiki-l] New 1.15.3 install

[Tolliver]

Hi,

I have a fresh install of Mediawiki 1.15.3, but I get a blank page when 
trying to access the test wiki. I've upgraded from Mediawiki 1.11.0.

Here is the error in the log file:
PHP Fatal error:  Call to private method User::loadFromSession() from 
context '' in 
/appl/web/devwiki/public_www/mediawiki-1.15.3/extensions/Auth_remoteuser.php 
on line 57


Current setup:
--------------
MediaWiki <http://www.mediawiki.org/>: 1.15.3
PHP <http://www.php.net/>: 5.1.6 (apache2handler)
MySQL <http://www.mysql.com/>: 5.0.77


Thanks
