Access denied for user - recently changed password - details in local.xml correct

Question

I recently changed the password for the admin user in MySQL. I updated the /app/etc/local.xml file to:

<connection>
    <host><![CDATA[<serverAddress>]]></host>
    <username><![CDATA[<username>]]></username>
    <password><![CDATA[<password>]]></password>
    <dbname><![CDATA[<dbName>]]></dbname>
    <initStatements><![CDATA[SET NAMES utf8]]></initStatements>
    <model><![CDATA[mysql4]]></model>
    <type><![CDATA[pdo_mysql]]></type>
    <pdoType><![CDATA[]]></pdoType>
    <active>1</active>
</connection>

When connecting to the home page it displays an error and the log number. Opening the log number I see:

a:4:{i:0;s:104:"SQLSTATE[HY000] [1045] Access denied for user 'username'@'ps251818.dreamhost.com' (using password: YES)";i:1;s:3125:"#0 /home/<username>/<homePage>/lib/Zend/Db/Adapter/Pdo/Mysql.php(96): Zend_Db_Adapter_Pdo_Abstract->_connect()

I have checked phpMyAdmin, and MySQL Workbench, the credentials provided are correct. Does it take time to propagate through from local.xml for the details to be used? The password has "@" in it, would this cause an issue? Example, in the local.xml file it looks something like:

<password><![CDATA[@bcDefghi1]]></password>

I don't know if this would cause an issue, but everything seems fine and I am clutching at straws.

You issue may in magento cache and Magento have cache ur database connection in cache. So need to flush magento cache by below process:

If you have magento cache store type file then you need to log ur magento Application Dir and then goes to it var/cache folder and delete all files from this folder

If you have using memcache or redis as cache store then you need to flush those cache by command line
