Thread:Extension talk:ConfirmEdit/ConfirmEdit results in Fatal Error

ConfirmEdit results in Fatal Error. I am using 1.18 and the 1.18 version of the extention.

Fatal error: Call to a member function addMessages on a non-object in /homepages/2/d276811108/htdocs/w/extensions/recaptcha/ConfirmEdit.php on line 172

Any clue what is going on? For now I will have to disable the extension.
