[Mediawiki-l] Upgrade problem

[Graham]

Hello,

I have upgraded my test wiki to Mediawiki 1.16.0, and the install completed without any issues. However, I get a error when trying to access the page. There isn't any errors in any of the log files.

This is what is displayed on the web page:
MediaWiki internal error.


Exception caught inside exception handler



This is what the log file shows:
[01/Oct/2010:10:31:04 -0300] "GET /wiki/index.php/Main_Page HTTP/1.1" 200 104 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8"


Current setup:
--------------
MediaWiki<http://www.mediawiki.org/>: 1.11.0
PHP<http://www.php.net/>: 5.1.6 (apache2handler)
MySQL<http://www.mysql.com/>: 5.0.77


Thank You.
