I'm a bit confused by the following:

My contact form works fine when logged in. But when not logged in, I get

Catchable fatal error: Argument 1 passed to QuestyCaptcha::getForm() must be an instance of OutputPage, none given, called in /www/htdocs/drebbel/wiki/extensions/ContactPage/ContactPage_body.php on line 433 and defined in /www/htdocs/drebbel/wiki/extensions/ConfirmEdit/QuestyCaptcha/QuestyCaptcha.class.php on line 44

My LocalSettings.php:

require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" );

require_once( "$IP/extensions/ConfirmEdit/QuestyCaptcha.php");

$wgCaptchaClass = 'QuestyCaptcha';

require_once "$IP/extensions/ContactPage/ContactPage.php";

$wgCaptchaTriggers['contactpage'] = true;

$wgContactConfig['default'] = array(

'RecipientUser' => 'xxxx', // a valid account which also has a verified e-mail-address added to it.

'SenderName' => 'Contact Form on ' . $wgSitename, // "Contact Form on" needs to be translated

'SenderEmail' => null, // Defaults to $wgPasswordSender, may be changed as required

'RequireDetails' => true, // Either "true" or "false" as required

'IncludeIP' => true, // Either "true" or "false" as required

'AdditionalFields' => array(

'Text' => array(

'label-message' => 'emailmessage',

'type' => 'textarea',

'rows' => 20,

'cols' => 80,

'required' => true, // Either "true" or "false" as required

),

),

// Added in MW 1.26

'DisplayFormat' => 'table',  // See HTMLForm documentation for available values.

'RLModules' => array(),  // Resource loader modules to add to the form display page.

'RLStyleModules' => array(),  // Resource loader CSS modules to add to the form display page.

);

If I change $wgContactConfig['default'] = array( into $wgContactConfig['contactpage'] = array( , I get

Contact form error
A contact form is either not configured for this page or is configured incorrectly.
