Thread:Project:Support desk/Innstalling Extension:CreativeCommonsRdf -- get error message.

Hi I have got an installation of mediawiki working and am now trying to install the Extension:CreativeCommonsRdf.

The installed versions are MediaWiki 1.17.0, PHP 5.3.5(apache2handler) and MySQL 5.1.53-log as reported by Extension:CreativeCommonsRdf.

The version on CreativeCommonsRdf is that downloaded from http://www.mediawiki.org/wiki/Extension:CreativeCommonsRdf

When I edit the LocalSettings.php file to include the extension, and go to the index page of the wiki I get a blank page. And the /var/log/apache2/error_log gets two new lines in it -

[Wed Sep 21 14:15:55 2011] [error] [client 192.168.1.67] PHP Notice: Undefined variable: dir in /srv/www/htdocs/wiki/4, referer: http://mouse/wiki/index.php/The_Sargent_Collection [Wed Sep 21 14:15:56 2011] [error] [client 192.168.1.67] PHP Fatal error: Call to undefined method MediaWiki::getActiativeCommonsRdf.php on line 17, referer: http://mouse/wiki/index.php/The_Sargent_Collection

I have looked around and cannot see anything that matches this, but then know very little about PHP, so dont know what I need to look for. What have I configured wrong !
