Member & Groups Show Wrong User Count

​I have created over 2000+ users in the system but now the member and group directory numbers are wrong. Member count shows 1 and Groups are all off too. I tried following the instructions to create a PHP file to add the below code in a new PHP file but nothing happened.

<?php

/** * Show All Site Members Count. */
function youzer_show_all_site_members_count() { return bp_get_total_site_member_count();
}

add_filter( ‘bp_get_total_member_count’, ‘youzer_show_all_site_members_count’ );

Please help!
