BuddyPress.org

I would like users to be redirected to the page they were originally on but it currently redirects to the homepage.

Here is my config, please could you let me know what I have done wrong?
<?php
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$MODE = MM_BUDDYPRESS_PRIVATE_COMMUNITY::MODE_BLOCK_NONE_AND_NOT_ALLOW_SOME_URIS;
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$ALLOWED_URIS = Array(‘/home’, ‘/noticeboard’, ‘register’);
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$NOT_ALLOWED_URIS = Array(‘/members’, ‘/teachers’);
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$REDIRECT_TO_URL = site_url() . ‘/register’;
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$REDIRECT_HOOK = ‘bp_pc_redir_to’;
MM_BUDDYPRESS_PRIVATE_COMMUNITY::$BLOCK_WIDGETS = FALSE;
