Hello,
You seem to have solved the problem. Thank you very much if you could explain the solution. Thank you again.

For me in functions.php, i changed this incorrect code:

function twentyten_posted_on() {
	printf( __( '<span class="%1$s">Posted on</span> %2$s <span class="meta-sep">by</span> %3$s', 'twentyten' ),
		'meta-prep meta-prep-author',
		sprintf( '<a href="%1$s" title="%2$s" rel="bookmark"><span class="entry-date">%3$s</span></a>',
			get_permalink(),
			esc_attr( get_the_time() ),
			get_the_date()
		),
		sprintf( '<span class="author vcard">%3$s</span>',
			get_author_posts_url( get_the_author_meta( 'ID' ) ),
			esc_attr( sprintf( __( 'View all posts by %s', 'twentyten' ), get_the_author() ) ),
			get_the_author()
		)
	);
}
endif;

To this correct code:

function twentyten_posted_on() {
	printf( __( '<span class="%1$s">Posted on</span> %2$s <span class="meta-sep">by</span> %3$s', 'twentyten' ),
		'meta-prep meta-prep-author',
		sprintf( '<a href="%1$s" title="%2$s" rel="bookmark"><span class="entry-date">%3$s</span></a>',
			get_permalink(),
			esc_attr( get_the_time() ),
			get_the_date()
		),
		sprintf( '<span class="author vcard"><a class="url fn n" href="%1$s" title="%2$s">%3$s</a></span>',
			get_author_posts_url( get_the_author_meta( 'ID' ) ),
			esc_attr( sprintf( __( 'View all posts by %s', 'twentyten' ), get_the_author() ) ),
			get_the_author()
		)
	);
}
endif;

Thank you very much
