In P2's functions.php, replace:

if( (false === $pos or $pos > 0) && $post->post_title != '')
 echo (is_single()) ? $before.$t.$after : $before.'<a href="'.$post->guid.'">'.$t.'</a>'.$after;

With:

if( (false === $pos or $pos > 0) && $post->post_title != '')
 echo (is_single()) ? $before.$t.$after : $before.'<a href="'.get_permalink( $post->id ).'">'.$t.'</a>'.$after;
