还是邮件确认的问题。
试了装1.9版本的，还是邮件确认有问题，在发送确认邮件的时候（也就是用户注册的最后一步），老师不成功；查了下错误，是这样说的：
Your moodle configuration is currently not able to send email. This is likely due to problems with your SMTP settings in the configuration file of your site. Please tell the administrator of your system to reconfigure this file, and try again.
如何在配置文件：config.php中修改呢？
盼大家多帮忙!
