The following code has been modified in the config.inc.php and config.sample.inc.php files

$cfg [' Servers '] [$i] [' controluser '] = ' root ';
$cfg [' Servers '] [$i] [' controlpass '] = ' my password ';

But the problem still arises?

------Solution--------------------
I have also had this problem.
The problem is either the wrong password or the database host error that you connected to the database is the $db_host value error.
------Solution--------------------
Set a username and password for the database, and give this user permission to access it.
------Solution--------------------
Attempt to perform a connection at the command line to confirm the correctness of the password

Follow the prompts #1045-access denied for user ' root ' @ ' localhost ' (using Password:no)
Indicates that no password was entered when connecting
------Solution--------------------
Look at the Data DB table and user table settings
------Solution--------------------
It helps you to look at this address! ~ ~
