I would greatly appreciate if you share the full single-portfolio.php template file with the sidebar option. This has been a frequent and popular requested in the theme by many purchased users.

Please help and Thank you for your time.

Here it goes, overwrite your single_portfolio with this:

<?php 
get_header(); ?>

<div class="row">
	<div class="sixteen columns">
	    <?php boc_breadcrumbs(); ?>
		<div class="page_heading mb0"><h1><?php the_title(); ?></h1></div>
	</div>
</div>

	<div class="row padded_block portfolio_page">
	
	<?php while(have_posts()): the_post(); ?>
		<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
			
			<?php
			$args = array(
			    'post_type' => 'attachment',
			    'numberposts' => '16',
			    'post_status' => null,
			    'post_parent' => $post->ID,
				'orderby' => 'menu_order',
				'order' => 'ASC',
				'exclude' => get_post_thumbnail_id()
			);
			$attachments = get_posts($args);
			if($attachments || has_post_thumbnail()):
			?>
	

		<?php // IF Post type is Standard (false) 	
		if(function_exists( 'get_post_format' ) && get_post_format( $post->ID ) != 'gallery' && get_post_format( $post->ID ) != 'video' && has_post_thumbnail()) { ?>

Then all you need to do is enable the custom sidebars for the Portfolio custom Post type – edit your includes/meta_boxes.php and sub this line:

'pages' => array( 'post','page','services'),

with this:

'pages' => array( 'post','page','services','portfolio'),

You are done, now just go to your Theme Options->Sidebars, create your new sidebars, add widgets to them from the Widgets screen then assign them to your portfolio items!
