Thread:Extension talk:Lockdown/permission error on Special:UserRights

Hello and exuse my english. Just installed Lockdown on MediaWiki 1.17.0. When entering as a bureaucrat who has 'userrights' privilege by default, there is a permission error on Special:UserRights, which claims i don't have such right to manage user rights. What could be the problem? Begging your pardon again. 81.30.184.63 17:56, 10 August 2011 (UTC)
