Hello there. I’ve found the Friends Suggest Plugin and downloaded the code from here since it was updated more recently: https://github.com/sbrajesh/bp-friends-suggest

I need to use it with the BP Follow plugin instead of the friend function. I’ve edited the code to work with BP Follow, but I’m facing an issue where the suggestions only show when the user is on another member’s profile. When visiting a member’s profile, it will suggest who to follow based on who the displayed member follows.

If a member is on another page like the homepage or the activity page, the widget shows “We don’t have enough details to suggest a friend yet”.

Also, if a member is on the page of another member who isn’t following anyone, the widget again shows “We don’t have enough details to suggest a friend yet”.

So the suggestions only show when visiting a member’s page who is following people that the logged in user is not.

Here is the edited code from bp-friend-suggest-widget.php

<?php

/**

class BP_Friend_Suggestions_Widget extends WP_Widget {

	public function __construct() {
		parent::__construct( false, $name = __( 'Friends Suggest Widget', 'bp-friends-suggest' ) );
	}

	public function widget( $args, $instance ) {
	
		
		if ( ! is_user_logged_in() ) {
			return; //do not show to non logged in user
		}
		
		extract( $args );
		
		echo $before_widget ;
		
		echo $before_title . $instance['title'] . $after_title ;
		
			bp_show_friend_suggestions_list( $instance['max'] );
			
		echo $after_widget;
	}

	public function update( $new_instance, $old_instance ) {
		
		$instance = $old_instance;
		$instance['title'] = strip_tags( $new_instance['title'] );
		$instance['max'] = absint( $new_instance['max'] );

		return $instance;
	}

	public function form( $instance ) {
		
		$instance = wp_parse_args( (array) $instance, array( 
					'title' => __( 'Friend Suggestions', 'bp-friends-suggest' ), 
					'max' => 5
					) 
		);
		
		
		$title = strip_tags( $instance['title'] );
		$max = absint( $instance['max'] );
		?>
		<p>
			<label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title', 'bp-friends-suggest' ); ?>
