Your link returns: Error establishing a database connection
Solutions:
1. Ensure that your domain is directed to your hosting provider
2. Check your database server
The “Error Establishing a Database Connection” message may surface on your WordPress site if your MySQL server is inactive. While various factors can trigger this error, an often encountered issue is an excessive number of connections.
A database server has a predetermined limit for the number of clients connected simultaneously. Once it reaches this maximum capacity, it may be unable to manage additional connections. Consequently, we advise reaching out to your hosting provider to inspect your MySQL server.
Log into your cPanel account, navigate to Files and choose File Manager. Inside public_html, create new file (test.php) and add following code:
<?php
$link = mysqli_connect(‘localhost’, ‘username’, ‘password’);
if (!$link)
{
die(‘Could not connect: ‘ . mysqli_error());
}
echo ‘Connected successfully’;
mysqli_close($link);
?>
Now access using browser: https://domain_name/test.php
3. Check the Database Login Credentials
Verify whether the database login settings align with those stored in your wp-config.php file. Access this file using the WordPress File Manager in your hosting control panel.
If the login information in your wp-config.php file differs from the MySQL database settings, synchronize them by making the necessary modifications to the wp-config file.
4. Fix the corrupted files:
File corruption can be a result of a defective theme or plugin. To determine the culprit causing the error, inspect these components individually. If the error surfaces after activating a new theme, the theme itself may be the source of the problem.
To address this issue, go to Appearance → Themes in your WordPress dashboard, and switch to a different theme.
If switching the theme does not resolve the “Error Establishing a Database Connection” issue, it could be stemming from a corrupted plugin.
Access the File Manager section in your cPanel dashboard. Navigate to public_html > wp_content and find the plugins folder. Right-click on the folder, and opt for the Rename option.
5. Repair the database in wordpress
Another issue that could lead to the “Error Establishing a Database Connection” in WordPress is a damaged database. This may occur due to data failures resulting from the frequent addition or removal of plugins or themes.
If your WordPress dashboard displays a message similar to “One or more database tables are unavailable. The database may need to be repaired,” it could indicate a corrupted database.
Add the following code in your wp_config.php file:
define(‘WP_ALLOW_REPAIR’, true);
