Theme "Bruneschelli": archive doesn't work

Hallo,

some weeks ago I installed the theme “Bruneschelli”. But unfortunatly the hyperlinks of the “archive” in the sidebar does not work at all. The links don’t guide to the list of posts / month. I just reach the “home”-site.

My archive.php:

<?php get_header(); ?>
		<div id="main" role="main" class="<?php brunelleschi_content_class(); ?>">

<?php
	if ( have_posts() )
		the_post();
?>

			<h1 class="page-title">
<?php if ( is_day() ) : ?>
				<?php printf( __( 'Daily Archives: <span>%s</span>', 'brunelleschi' ), get_the_date() ); ?>
<?php elseif ( is_month() ) : ?>
				<?php printf( __( 'Monthly Archives: <span>%s</span>', 'brunelleschi' ), get_the_date( 'F Y' ) ); ?>
<?php elseif ( is_year() ) : ?>
				<?php printf( __( 'Yearly Archives: <span>%s</span>', 'brunelleschi' ), get_the_date( 'Y' ) ); ?>
<?php else : ?>
				<?php _e( 'Blog Archives', 'brunelleschi' ); ?>
<?php endif; ?>
			</h1>
<?php
	rewind_posts();
get_template_part( 'loop', 'archive' );
?>
		</div><!-- #main -->
<?php if( brunelleschi_option('sidebar') === 'both'
		|| brunelleschi_option('sidebar') === 'two left'
		|| brunelleschi_option('sidebar') === 'two right'){
			get_sidebar('secondary');
		} ?>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

My loop.php:

[ ... ]
<?php if ( is_archive() || is_search() ) : // Display excerpts for archives and search. ?>
			<div class="entry-summary">
				<?php if( brunelleschi_option('archives-format') === '1' ){ the_content(); }else{ the_excerpt(); } ?>
			</div><!-- .entry-summary -->
		<?php else : ?>
			<div class="entry-content">
				<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'brunelleschi' ) ); ?>
			</div><!-- .entry-content -->
		<?php endif; ?>

			<div class="entry-utility">
				<?php brunelleschi_posted_on(); ?>
				<span class="meta-sep">|</span>
				<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'brunelleschi' ), __( '1 Comment', 'brunelleschi' ), __( '% Comments', 'brunelleschi' ) ); ?></span>
				<?php edit_post_link( __( 'Edit', 'brunelleschi' ), '<span class="meta-sep">|</span> <span class="edit-link">', '</span>' ); ?>
			</div><!-- .entry-utility -->
		</aside><!-- #post-## -->

	<?php else : ?>
		<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
			<header>
				<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'brunelleschi' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>
				<?php if(brunelleschi_option('posted-on') === 'Above Post'): ?>
				<div class="entry-meta">
					<?php brunelleschi_posted_on(); ?>
				</div><!-- .entry-meta -->
				<?php endif; ?>
			</header>
	<?php if ( is_archive() || is_search() ) : ?>
			<div class="entry-summary">
				<?php if( brunelleschi_option('archives-format') === '1' ){ the_content(); }else{ the_excerpt(); } ?>
			</div><!-- .entry-summary -->
	<?php else : ?>
			<div class="entry-content">
				<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'brunelleschi' ) ); ?>
				<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'brunelleschi' ), 'after' => '</div>' ) ); ?>
			</div><!-- .entry-content -->
	<?php endif; ?>
[ ... ]
and so on ...

How can I correct this mistake? If you need my complet loop.php or another template for your help, I can hand it too.

Thanks in advance.
