Can’t select database: not able to select the ****** database

I don’t know where the problem is. It’s been driving me crazy all day!
Please help.
———————————————————————
This is the error message:
We were able to connect to the database server (which means your username and password is okay) but not able to select the ****** database.

Are you sure it exists?
Does the user @@@@@ have permission to use the ****** database?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?

——————————————————————-
This is my wp-config.php file:

<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘******’); // The name of the database
define(‘DB_USER’, ‘@@@@@’); // Your MySQL username
define(‘DB_PASSWORD’, ‘——‘); // …and password
define(‘DB_HOST’, ‘******.db’); // 99% chance you won’t need to change this value–>I changed it!
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);

// Change each KEY to a different unique phrase. You won’t have to remember the phrases later,
// so make them long and complicated. You can visit http://api.ww.wp.xz.cn/secret-key/1.1/
// to get keys generated for you, or just make something up. Each key should have a different phrase.
define(‘AUTH_KEY’, ‘[email protected]{)o_}m*O\\_;\”xqQLTvxT_ $FFur =Dtw)[xs(|JwAdl(M8y’); // Change this to a unique phrase.
define(‘SECURE_AUTH_KEY’, ‘6DN%zzFiz97L_XA|MLJ&t8W&!<6_6PacqCgF)\”7)\Md1y+]gi\”A-C5R*Y(Xsg8yB’); // Change this to a unique phrase.
define(‘LOGGED_IN_KEY’, ‘I75A~9FHcg;p&f8 :1Mf\]*=[:;5+jz-h2OR%\\yFC7s +K!q+ !*)m’); // Change this to a unique phrase.

// You can have multiple installations in one database if you give each a unique prefix
$table_prefix = ‘wp_’; // Only numbers, letters, and underscores please!

// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-content/languages.
// For example, install de.mo to wp-content/languages and set WPLANG to ‘de’
// to enable German language support.
define (‘WPLANG’, ”);

/* That’s all, stop editing! Happy blogging. */

if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(__FILE__) . ‘/’);
require_once(ABSPATH . ‘wp-settings.php’);
?>
