Fragment of a discussion from Extension talk:ConfirmEdit
You're probably using an older version of MediaWiki, that's not supported by the latest version of ConfirmEdit any more.
Then, why does the Extension page state the current release of ConfirmEdit supports MW 1.11 and later? I'm having the same problem, on a MW 1.15-based system.
It definitely doesn't support MW 1.11 - I'm not even sure if it supports MW 1.17, or if it's only MW 1.18. That "1.11" should probably be changed - I guess it's there to indicate that there are older versions of ConfirmEdit going back to 1.11; or maybe it's just that no one bothered to change it.
You should download the version of ConfirmEdit appropiate for your MediaWiki version (which is indeed an old version of ConfirmEdit).
