hi @millir,

give this a try:
tested on wp 4.0 bp 2.0.2 theme 2013 – snippet is in bp-custom.php

/*activity stream on homepage */
if (!function_exists('wwn_bp_activities')) {
    function wwn_bp_activities( ) {
		ob_start();
		
		// Remove 'bp_replace_the_content' filter to prevent infinite loops
		remove_filter( 'the_content', 'bp_replace_the_content' );
		if ( bp_has_activities( bp_ajax_querystring( 'activity' ) . 'per_page=5' ) ) :
		bp_get_template_part( 'activity/index' );
		
		// Remove 'bp_replace_the_content' filter to prevent infinite loops
		add_filter( 'the_content', 'bp_replace_the_content' );
		
		// Get the output buffer contents
		$output = ob_get_clean();
		
		// Echo or return the output buffer contents
		if ( true === $echo ) {
			echo $output;
		} else {
			return $output;
		}
		endif;	
		
		ob_end_clean();
	
}
add_shortcode('wwn_bp_activities', 'wwn_bp_activities');
}

You’re using ob_start() and ob_end_clean() in the wrong manner.

You need to save the contents of the activity loop into a variable and then return the contents for the shortcode to work.

Something like:

ob_start();

// THE CODE YOU HAVE FOR THE ACTIVITY LOOP

// this is the part you're missing
$output = ob_get_contents();

ob_end_clean();

// this is the part you're missing
return $output;

@millir,
I tested your function and nothing is returned.

to get the activities, i changed
$output .= locate_template( array( 'activity/entry.php' ), true, false );

to
$output .= bp_get_template_part( 'activity/entry' );

thank you for that clarification @r-a-y
