Thread:Extension talk:CheckUser/How to install CheckUser for MediaWiki 1.16.5 ?/reply (2)

Thank you for your reply.

1. I tried to copy and past the code from http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/CheckUser/ to my extensions/CheckUser folder.

2. Set AdminSettings.php with my valid username and password in my root. $wgDBadminuser     = 'ChangeToMywikiadmin'; $wgDBadminpassword = 'ChangeToMyadminpass';

3. Add the code below in my LocalSettings.php. require_once ( "$IP/extensions/CheckUser/CheckUser.php" );

When I browse my Special:CheckUser web page, got the error message below: Fatal error: Call to undefined method CheckUser::checkPermissions
