Thread:Extension talk:Lockdown/possible conflict with ConfirmAccount extension?

Hi again, i using MediaWiki 1.17.0 and have installed both Lockdown and ConfirmAccount extensions. Without ConfirmAccount included in, Lockdown works excellent, and vice versa. But if included along, they does a common error, when registered user groups ('user', 'sysop' etc.) have rights as ' * ' group, not more. I have changed  to , like it was recommended below, but it didn't help. Can you please help me?
