2. Check Your Database Credentials

To build up an association with the information base, your WordPress site should give precise sign in subtleties through the wp-config.php document. In the event that that doesn’t occur, you’ll see “Blunder building up an information base association.”

Open your wp-config.php document and find this part:

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'vistxxx_wpxxx' );

/** MySQL database username */
define( 'DB_USER', 'vistxxx_wpxxx' );

/** MySQL database password */
define( 'DB_PASSWORD', 'pkxxxxxxxx' );

/** MySQL hostname */
define( 'DB_HOST', 'localhost' );

Open your #1 code editorial manager (I love Notepad++), and add the accompanying code into another record:

<?php
$test = mysqli_connect('localhost', 'db_user', 'db_password');
if (!$test) {
die('MySQL Error: ' . mysqli_error());
}
echo 'Database connection is working properly!';
mysqli_close($testConnection);
