## The current username, password or host was not accepted ...

```
TYPO3 Fatal Error: The current username, password or host
was not accepted when the connection to the database was
attempted to be established!

```

### Correct the database settings

Check your `LocalConfiguration.php` or `AdditionalConfiguration.php` files and verify
that the database connection settings are correct.

### Restart the MySQL daemon.

1.  Login as root on your system if you have shell access, or start a console from the server panel.
1.  type: /etc/init.d/mysql restart
    On Mac OSX 10.10 (Yosemite) type:
    sudo /usr/local/mysql/support-files/mysql.server stop
1.  If you get this error:

    ```
    ERROR! The server quit without updating PID file (/usr/local/mysql/data/<SERVERNAME>.pid)

    ```

    Then your next option is to kill the mysql process manually by following this instructions:
    [http://stackoverflow.com/questions/26263889/starting-mysql-error-the-server-quit-without-updating-pid-file/26266079#26266079](http://stackoverflow.com/questions/26263889/starting-mysql-error-the-server-quit-without-updating-pid-file/26266079#26266079)
1.  Then restart mysql daemon again. This time it should work.
    On Mac OSX 10.10 (Yosemite) type:
    sudo /usr/local/mysql/support-files/mysql.server start

### TYPO3 6.2 - modify your MySQL configuration file

The problem could depend on recent PHP update from v. 5.3/5.4 to 5.5; a new module is installed: php-mysqlnd. So your TYPO3 attempt to establish a db connect but mysql do not use more your old encryption method for the password.

Proceed as follows:

1.  edit /etc/my.cnf
1.  remove the old_passwords=1 statement
1.  login as root in your server
1.  login to mysql as admin/root (mysql -u root -p)
1.  select database, type: use mysql;
1.  just switched to mysql db change the password of the user:

    ```
    update mysql.user set password=PASSWORD('password') where user='db-username'

    ```

    obviously substitute db-username with the 'username' and 'password' with the right (old or new password) used to access your db, stored in: typo3conf/LocalConfiguration.php
1.  restart your mysql daemon: /etc/init.d/mysqld restart
1.  eventually remove all site cache: rm -rif typo3temp/Cache\*
