[MediaWiki-l] Help Hiding the Toolbox for unregistered users

Greetings:

I used this code that I found here: https://www.mediawiki.org/wiki/Manual:Interface/Sidebar#content_of_sidebar_a...

<?php $wgHooks['SkinBuildSidebar'][] = 'lfHideSidebar'; function lfHideSidebar( $skin, &$bar ) { global $wgUser; // Hide sidebar for anonymous users if ( !$wgUser->isLoggedIn() ) { $bar = array( 'navigation' => array( array( 'text' => wfMsg( 'login' ), 'href' => SpecialPage::getTitleFor( 'Login' )->getLocalURL(), 'id' => 'n-login', 'active' => '' ) ) ); } return true; }

When I tried to access my wiki I got the white page of death.

I am using MW 1.21.1

Looking for help with this code or a better way to hide the sidebar for anonymous users.

Thanks,

Wade
