/*

For login/logout redirection:

Edit punbb's login.php


Find: $page_title = pun_htmlspecialchars($pun_config['o_board_title']).' / '.$lang_common['Login'];

Add before it: $redirect_url = (isset($_GET['redir'])) ? $_GET['redir'] : $redirect_url;


Find: redirect('index.php', $lang_login['Logout redirect']);

Change to: redirect(isset($_GET['redir']) ? $_GET['redir'] : 'index.php', $lang_login['Logout redirect']);
