Thread:Project:Support desk/Private Wiki with accessible Special:ConfirmEmail/reply (6)

You should not need to list the subpage of Special:ConfirmEmail in the whitelist (I believe, otherwise things are rather broken for wikis that use your setup, and I would consider that a bug ;) )

Also if your wiki is not english, you may need to use the localized version of the special page name.

Have you read Manual:$wgReadWhitelist?
