placemark-post 404 error

Hi, When i try to show placemarks post then return 404 error. What can i do to fix that. I’v also a list of placemarks under a map with link to each placemark with this same effect – 404 error. there is at all a possibility to see a placemarks like ordinary post?
my shortcode-bgmp-list-marker file looks like this:

<li id="<?php esc_attr_e( self::PREFIX ); ?>list-item-<?php esc_attr_e( $p->ID ); ?>" class="<?php esc_attr_e( self::PREFIX ); ?>list-item">
	<h3 class="<?php esc_attr_e( self::PREFIX ); ?>list-placemark-title">
		<?php echo apply_filters( 'the_title', $p->post_title ); ?>

		<?php if( $viewOnMap ) : ?>
			<span class="<?php esc_attr_e( self::PREFIX ); ?>view-on-map-container">
				[<a href=";">ID ); ?>" class="<?php esc_attr_e( self::PREFIX ); ?>view-on-map">View On Map</a>]
			</span>
		<?php endif; ?>
	</h3>
<div class="<?php esc_attr_e( self::PREFIX ); ?>list-description">
		<?php /* note: don't use setup_postdata/get_the_content() in this instance -- http://lists.automattic.com/pipermail/wp-hackers/2013-January/045053.html */ ?>
		<?php echo apply_filters( 'the_content', $p->post_content ); ?>
	</div>

	<p class="<?php esc_attr_e( self::PREFIX ); ?>list-link">
		<a>">
			<?php echo wp_kses( $address, wp_kses_allowed_html( 'post' ) ); ?>
		</a>
	</p>

<li class="<?php esc_attr_e( self::PREFIX ); ?>list-item">
	<div class="<?php esc_attr_e( self::PREFIX ); ?>list-placemark-title">
		<a>ID ); ?>">
	<?php echo apply_filters( 'the_title', $p->post_title ); ?>
</a>
	</div>
