I have activated the extension ContactPage for the wiki named wpe. Also I have set the additional setting $wmgContactPageRecipientUser (under notifications tab) to user Driolar (thats me). Now, invoking https://wpe.miraheze.org/wiki/Special:Contact shows a form with name, email address and subject fields to be filled. But the body field is missing! Curiously, the subject field is prefilled with the text "Contact message". This presetting would rather fit to the (missing) body or message field. May be the $wgContactConfig variable is broken?
