Check Database Credentials
To troubleshoot the ‘Error Establishing a Database Connection’ in WordPress, the first step is to check your database credentials. Make sure you have entered the correct database name, username, password, and host in your WordPress configuration file. It’s also important to double-check that the database user has the necessary privileges to access the database. If you’re not sure about the credentials, you can refer to the documentation provided by your web hosting provider.

By verifying and correcting your database credentials, you can resolve this error and get your WordPress site back up and running.
Verify Database Server Status
To verify the database server status, you can use the phpMyAdmin tool or access the database server through the command line. If you are using phpMyAdmin, you can check the server status by logging in and selecting the server from the left-hand side panel. Once you are on the server page, you can see the server status on the right-hand side. If the server status is offline or not running, it indicates that there is an issue with the database server. In this case, you can try restarting the server or contacting your hosting provider for assistance.
Test Database Connection
To test the database connection, you can use the wp-config.php file in your WordPress installation. Open the file and find the section that contains the database configuration settings. Make sure the database name, username, password, and host are correct. If any of the values are incorrect, update them accordingly. Once you’ve made the necessary changes, save the file and refresh your website to see if the error is resolved.

If you’re experiencing the ‘Error Establishing a Database Connection’ in WordPress, increasing the PHP memory limit can help resolve the issue. This error can occur when the memory allocated to PHP is not sufficient to handle the database connection. To increase the PHP memory limit, you can modify the php.ini file or add a line of code to the wp-config.php file. Make sure to set the memory limit to a value that is suitable for your website’s requirements. Additionally, you can also try disabling any unnecessary plugins that might be consuming excessive memory.
