Topic on Extension talk:ConfirmAccount

To avoid this, you must change: /ConfirmAccount/business/AccountConfirmSubmission.php.

Function createUserpage() the last part must look like this

#Create userpage!
if( !empty($body) ) {  // <- new
$article = new WIkiPage( ...
$article->doEdit( ...
}  // <- new

I'll just make a patch for that in gerrit.
