ok, remove the whole line

<?php echo do_shortcode(‘[bbpress_recent_replies_by_topic show =5]’) ?>

then add this to your functions

add_action( 'bbp_template_before_forums_loop', 'call_bbpress_recent_replies_by_topic' ); 

function call_bbpress_recent_replies_by_topic () {
	echo do_shortcode("[bbpress_recent_replies_by_topic show=5]") ;
}

This just hooks to the line after the one you’d added

<?php do_action( ‘bbp_template_before_forums_loop’ ); ?>

so saving you having to amend that template.

This works on my site.
