Onethink database connection failed, always prompt for incorrect password resolution

The Onethink database configuration file is \application\common\conf\ config.php, supposedly, here to modify the database configuration should be able to reconnect, but no matter how I change the password is always inconsistent with my settings, find a lot of information on the Internet can not solve my problem, but the word "cache" reminds me, so I put the cache directory file after all deleted, The printing configuration information is correct, but after the comment printed code, and then the previous configuration information, and then found in the Portal file solution, the original Onethink the previous installation of the database connection user name and password was cached so how can not even, decisive in \application\ user\conf\config.php file modified define (' Uc_db_dsn ', ' mysqli://root:[email protected]:3306/onethink '); OK, everything works!!! (Note: 123456 after root is the modified password)
