remove_menu_page doesn't work

[czepol]

Probably a mistake. Maybe I'm doing something wrong, but:

<?php

require_once(ABSPATH . 'wp-admin/includes/admin.php');

remove_menu_page( 'link-manager.php' );

?>

This code returns error:
Warning: Invalid argument supplied for foreach() in /var/www/3.1/app/wp-admin/includes/plugin.php on line 1263

plugin.php:1263:

foreach ( $menu as $i => $item ) {

This code returns NULL:

global $menu;
var_dump($menu);

That's cause $menu isn't set up yet. You need to wait until the admin_menu hook or so.

Not sure why you're including includes/admin.php outside of an example. You'd really only ever include that in rare cases (read: never), and in those cases you wouldn't have a menu initialized.
