Bug & Possible Fix: Can't login on some systems

When deploying to wpengine.com, I found I couldn’t log in as super admin if my site was down, even though it had worked fine on my dev box. I had also discovered a case of where your could trick a the plugin to show a page by hacking the url. I think the following might be a good update for in the ‘shutdown’ function: //jjr better login detection -begin- # Motivation: # 1) handle case of wp-admin/page=update.php?ILoveHacking&blah=wp-login.php # 2) On standard wpengine.com multi-site install, could not login as site admin while in maint mode #if ($wpdb->blogid == 1 && $this->urlend('wp-login.php')) return; //I told you *not* to log out, but you did anyway. duh! global $pagenow; $isAtRootLogin = ($wpdb->blogid == 1 && $pagenow == 'wp-login.php'); if ($isAtRootLogin) { return; //I told you *not* to log out, but you did anyway. duh! } // jjr -end- https://wordpress.org/plugins/wpms-site-maintenance-mode/
