    I have Attitude Pro 1.2 with a Child Theme here: http://injestfestival.com/
    I’ve added your code to the child’s functions.php to have post titles in the breadcrumbs bar and to add the child_services widget, so that the services widgets’ titles are clickable. I’ve included that code below. But first, this is the type of error I get when navigating around dashboard, which makes editing impossible unless I temporarily disable the child’s functions.php file (I’ve replaced text with “xxx” in case it’s sensitive info.)

    Thanks!
    I ended up switching the order of functions in my child’s functions.php, and now it all works without the error.
    Here’s the code I use in child’s functions.php to put page titles in the breadcrumbs bar and to create a services_child widget that allows the titles of the services to be clickable:

    <?php
function attitude_header_title() {
	if( is_archive() ) {
		$attitude_header_title = single_cat_title( '', FALSE );
	}
	elseif( is_404() ) {
		$attitude_header_title = __( 'Page NOT Found', 'attitude' );
	}
	elseif( is_search() ) {
		$attitude_header_title = __( 'Search Results', 'attitude' );
	}
	elseif( is_page_template()  ) {
		$attitude_header_title = get_the_title();
	}

	elseif( is_page()  ) {
		$attitude_header_title = get_the_title();
	}

	else {
		$attitude_header_title = '';
	}

	return $attitude_header_title;

}
function attitude_theloop_for_page() {
	global $post;

	if( have_posts() ) {
		while( have_posts() ) {
			the_post();

			do_action( 'attitude_before_post' );
?>
	<section id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
		<article>

			<?php do_action( 'attitude_before_post_header' ); ?>

  			<?php do_action( 'attitude_after_post_header' ); ?>

  			<?php do_action( 'attitude_before_post_content' ); ?>

  			<div class="entry-content clearfix">
    			<?php the_content(); ?>
    			<?php
    				wp_link_pages( array( 
						'before'            => '<div style="clear: both;"></div><div class="pagination clearfix">'.__( 'Pages:', 'attitude' ),
						'after'             => '</div>',
						'link_before'       => '<span>',
						'link_after'        => '</span>',
						'pagelink'          => '%',
						'echo'              => 1 
               ) );
    			?>
  			</div>

  			<?php 

  			do_action( 'attitude_after_post_content' );

  			do_action( 'attitude_before_comments_template' ); 

         comments_template(); 

         do_action ( 'attitude_after_comments_template' );

         ?>

		</article>
	</section>
<?php
			do_action( 'attitude_after_post' );

		}
	}
	else {
		?>
		<h1 class="entry-title"><?php _e( 'No Posts Found.', 'attitude' ); ?></h1>
      <?php
   }
}
?>
