Hi Sotiris,

Thank you for confirming.

The suggestion is a service provided by BuddyPress and only client side is enabled by the theme.

It is possible to make it friends only but that will make the suggestions at other places friends only too.

Here is a couple of line you can put in bp-custom.php or your child theme’s function.php

/**
 * Make suggestions friends only.
 */
add_filter( 'bp_members_suggestions_args', function ( $args ) {
	$args['only_friends'] = true;

	return $args;
} );

You are welcome. I am glad it is resolved. I sincerely appreciate your help in identifying and resolving it.
