Some time, your MySQL server die unexpectedly, you don’t have any plan for it and this is what you’ll get
ugly huh ? i personally hate this error message a lot. so i decided to turn it to something better, make me feel comfortable and give me chances to fix this issue.
if you look at wp-includes/functions.php, line 2710, there’s a dead_db function
function dead_db() {
global $wpdb;
// Load custom DB error template, if present.
if ( file_exists( WP_CONTENT_DIR . '/db-error.php' ) ) {
require_once( WP_CONTENT_DIR . '/db-error.php' );
die();
}
// If installing or in the admin, provide the verbose message.
if ( defined('WP_INSTALLING') || defined('WP_ADMIN') )
wp_die($wpdb->error);
// Otherwise, be terse.
status_header( 500 );
nocache_headers();
header( 'Content-Type: text/html; charset=utf-8' );
wp_load_translations_early();
?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"<?php if ( is_rtl() ) echo ' dir="rtl"'; ?>>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title><?php _e( 'Database Error' ); ?></title>
</head>
<body>
<h1><?php _e( 'Error establishing a database connection' ); ?></h1>
</body>
</html>
<?php
die();
}
there it is, you can have a db error template for that ugly message. From here, what you need to do is creating your own message. this is mine :
