WP Listings sidebar missing

Hello – I am installed the WP Listings plugin on my WordPress website using the Avada theme.

Problem: I can’t get a sidebar to show up on the single listings page. I tried copying the file single-listing.php into wp-content/themes/Avada-Child-Theme and Avada folders. The code at the bottom of that file says:

<?php
get_sidebar( ‘content’ );
get_sidebar( ‘content’ );
get_footer();

}

Under “Avada options” on the “Edit Listing” screen, I have selected a sidebar (Property Search), position: right, but it does not show up. It seems like there is space for a sidebar, but no content. Any tips?

Here is a page with an example of the correct sidebar – this one uses a different property listings plug-in: http://lewisedc.com/wordpress/commercial/axelson-building/

Thank you!
