2011 child theme does not show custom template

@michael:

Sorry, i forgot it, here is my template code, its named “sidebarpage-template.php” :

<?php
/**
 * Template Name: Sidebar Page
 * Description: Template for displaying all pages with sidebar (single sidebar page, not single post !)
 *
 * @package WordPress
 * @subpackage Twenty_Eleven
 * @since Twenty Eleven 1.0
 */

get_header(); ?>

		<div id="primary">
			<div id="content" role="main">

				<?php while ( have_posts() ) : the_post(); ?>

					<?php get_template_part( 'content', 'page' ); ?>

					<?php comments_template( '', true ); ?>

				<?php endwhile; // end of the loop. ?>

			</div><!-- #content -->
			<?php get_sidebar(); ?>
		</div><!-- #primary -->

<?php get_footer(); ?>
