			<?php if ( ! dynamic_sidebar( 'sidebar-1' ) ) : ?>

				<aside id="search" class="widget widget_search">
					<?php get_search_form(); ?>
				</aside>

				<aside id="archives" class="widget">
					<h1 class="widget-title"><?php _e( 'Archives', 'Formation' ); ?></h1>

<ul>
						<?php wp_get_archives( array( 'type' => 'monthly' ) ); ?>
					</ul>
                                            <aside id="meta" class="widget">
					<h1 class="widget-title"><?php _e( 'Meta', 'Formation' ); ?></h1>

<ul>
						<?php wp_register(); ?>

<li><?php wp_loginout(); ?></li>
						<?php wp_meta(); ?>
					</ul>
				</aside>

			<?php endif; // end sidebar widget area ?>
		</div><!-- #secondary .widget-area -->
