How to remove the links on the meta widget

Paste this in your functions.php

// Widget: Meta; to match the Sandbox style and replace Widget plugin default
function widget_sandbox_meta($args) {
	extract($args);
	$options = get_option('widget_meta');
	$title = empty($options['title']) ? __( 'Meta', 'sandbox' ) : $options['title'];
?>
			<?php echo $before_widget; ?>
				<?php echo $before_title . $title . $after_title; ?>
				<ul>
					<?php wp_register() ?>

					<li><?php wp_loginout() ?></li>
					<?php wp_meta() ?>

				</ul>
			<?php echo $after_widget; ?>
<?php
}

I forgot a part…also add this code:

// Widgets plugin: intializes the plugin after the widgets above have passed snuff
function sandbox_widgets_init() {
	// Sandbox Meta widget
	$widget_ops = array(
		'classname'    =>  'widget_meta',
		'description'  =>  __( "Log in/out and administration links (Sandbox)", "sandbox" )
	);
	wp_register_sidebar_widget( 'meta', __( 'Meta', 'sandbox' ), 'widget_sandbox_meta', $widget_ops );
	unregister_widget_control('meta');
	wp_register_widget_control( 'meta', __('Meta'), 'wp_widget_meta_control' );
}

// Runs our code at the end to check that everything needed has loaded
add_action( 'init', 'sandbox_widgets_init' );

It should look something like this:

// Widget: Meta; to match the Sandbox style and replace Widget plugin default
function widget_sandbox_meta($args) {
	extract($args);
	$options = get_option('widget_meta');
	$title = empty($options['title']) ? __( 'Meta', 'sandbox' ) : $options['title'];
?>
			<?php echo $before_widget; ?>
				<?php echo $before_title . $title . $after_title; ?>
				<ul>
					<?php wp_register() ?>

					<li><?php wp_loginout() ?></li>
					<?php wp_meta() ?>

				</ul>
			<?php echo $after_widget; ?>
<?php
}

// Widgets plugin: intializes the plugin after the widgets above have passed snuff
function sandbox_widgets_init() {
	// Sandbox Meta widget
	$widget_ops = array(
		'classname'    =>  'widget_meta',
		'description'  =>  __( "Log in/out and administration links (Sandbox)", "sandbox" )
	);
	wp_register_sidebar_widget( 'meta', __( 'Meta', 'sandbox' ), 'widget_sandbox_meta', $widget_ops );
	unregister_widget_control('meta');
	wp_register_widget_control( 'meta', __('Meta'), 'wp_widget_meta_control' );
}

// Runs our code at the end to check that everything needed has loaded
add_action( 'init', 'sandbox_widgets_init' );

Try to remove anything else from that file first (but keep it somewhere), and try it out.

Damn…I forgot to add the opening and closing tags.

<?php
// Widget: Meta; to match the Sandbox style and replace Widget plugin default
function widget_sandbox_meta($args) {
	extract($args);
	$options = get_option('widget_meta');
	$title = empty($options['title']) ? __( 'Meta', 'sandbox' ) : $options['title'];
?>
			<?php echo $before_widget; ?>
				<?php echo $before_title . $title . $after_title; ?>
				<ul>
					<?php wp_register() ?>

					<li><?php wp_loginout() ?></li>
					<?php wp_meta() ?>

				</ul>
			<?php echo $after_widget; ?>
<?php
}

// Widgets plugin: intializes the plugin after the widgets above have passed snuff
function sandbox_widgets_init() {
	// Sandbox Meta widget
	$widget_ops = array(
		'classname'    =>  'widget_meta',
		'description'  =>  __( "Log in/out and administration links (Sandbox)", "sandbox" )
	);
	wp_register_sidebar_widget( 'meta', __( 'Meta', 'sandbox' ), 'widget_sandbox_meta', $widget_ops );
	unregister_widget_control('meta');
	wp_register_widget_control( 'meta', __('Meta'), 'wp_widget_meta_control' );
}

// Runs our code at the end to check that everything needed has loaded
add_action( 'init', 'sandbox_widgets_init' );
?>
