修改了禅道数据库权限后，访问禅道时提示数据库没有权限，具体描述见下面已解决悬赏50积分

我在禅道数据库网页管理页面执行了一下mysql授权的语法，语法如下：

 1. GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH

      GRANT OPTION;  

  2.FLUSH   PRIVILEGES; 

并修改了my.ini，注释掉了bind-address = 127.0.0.1

然后在浏览器访问禅道，报以下错误：

21:37:47 ERROR: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES) in C:\xampp\xampp\zentao\framework\base\router.class.php on line 2165, last called by C:\xampp\xampp\zentao\framework\base\router.class.php on line 2116 through function connectByPDO.
