安装appserv后无法进入系统，白屏已解决 悬赏5积分

请问下，先装了禅道：ZenTaoPMS.7.0.stable.exe，再装appserv：appserv_8.0.0.1454401891.exe，装完后进禅道白屏。

修改my.php中$config->debug= true;出现日志：

00:08:56 ERROR: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) in D:\PMS\xampp\zentao\framework\router.class.php on line 1506, last called by D:\PMS\xampp\zentao\framework\router.class.php on line 1468 through function connectByPDO.

修改xampp\phpmyadmin下config.inc.php：$cfg['Servers'][1]['password'] 为安装appserv时的Mysql密码,发现数据还在，如下图。请问有办法让禅道能恢复正常吗？谢谢！
