Check Your Database Credentials
As we discussed earlier, when you encounter the "Error Establishing a Database Connection" message on your WordPress website, it usually means that WordPress cannot access the database. This can happen for a variety of reasons, but one of the most common causes is incorrect database credentials. Database credentials are the login details that WordPress uses to connect to your website's database.
These details consist of the username, database name, password, and host. If any of these details are incorrect, WordPress won't be able to connect to the database, resulting in the "Error Establishing a Database Connection" prompt. To fix this error, you'll need to verify that your database credentials are correct. WP-config file contains all of your website's configuration settings, including your database credentials.
You can locate it in the root directory of your site’s WordPress installation. Open the file and verify that the database name, username, password, and host are correct. In your hosting account’s control panel, you can check for the username and password you have specified. If they are incorrect, WordPress won’t be able to make a connection with your site’s database. Hence, make sure to mention the username and password correctly.
Check Your Database Host Information
Another possible reason behind getting the “error establishing database connection” on your WordPress website could be incorrect database host information. The database host is the server that stores your website’s database. Incorrect database host information makes it unable for WordPress to connect to the right database host.
As a result, you encounter the “error establishing a database connection” message on your WordPress website. Therefore, it is essential to check the database host information to get rid of the database connection error. Here are some simple steps to check and fix the database host information of your website.
Verify the Hostname
The database hostname is typical "localhost" if your website is hosted on the same server as your database. If your website is hosted on a different server, then you need to use the hostname provided by your hosting provider. Make sure that the hostname in your wp-config.php file is the same as your database server and spelled correctly.
Check the Database Port
The database port acts as a medium of communication to the database over any network. By default, the MySQL database uses port 3306. However, some hosting providers may use a different port. Due to the use of a different port, WordPress becomes unable to make a connection with the database. Hence, if your hosting provider uses a different port, you will need to specify it in your wp-config.php file.
Check Firewall Settings
If you have a firewall installed on your server, it's possible that it's blocking the database connection. To ensure a smooth connection to the database, make sure to whitelist the IP address of your web server to allow access to the database host. By following these steps, you can easily check and fix any issues with your database host information, and resolve the "Error Establishing a Database Connection" message on your WordPress website.
If you've checked all of these settings and they're correct, but you're still getting the "Error Establishing a Database Connection" message, it's possible that there's an issue with your hosting provider's database server. In this case, you should contact your hosting provider's support team for further assistance.
Repair the Database
If you are experiencing the "Error Establishing a Database Connection" message on your WordPress website, it may be caused due to a corrupted or damaged database. It can corrupt due to a variety of reasons such as server crashes, plugin conflicts, or incomplete updates. In such a scenario, repairing the database is a potential solution to fix the database connection issue.
Before attempting to repair your database, it is crucial to create a backup of your database to avoid losing any data. You can use a plugin or access your hosting provider's backup tool to create a backup. Login to your hosting account and locate the phpMyAdmin tool.
This tool is available in the cPanel dashboard. Once you've accessed phpMyAdmin, select the database that is associated with your WordPress installation. You can repair your database by clicking on the "Repair" button that appears on the screen. This will run a repair operation on your database and fix any errors or corruption that may be causing the "Error Establishing a Database Connection" message.
After repairing the database, check your website to ensure that the error message has been resolved. Sometimes, the error may continue to occur due to cached data. In this case, try clearing your browser's cache and cookies and reloading your website.
Check Whether Your Database Server is Offline
If your database server is offline, your website will not be able to connect to the database server. Hence, it is necessary to check the online status of your database server before initiating a connection to it. The first step is to check if your website is accessible. If your website is not accessible, then it's likely that your database server is offline.
If you have access to your server, you can check the status of the database server by logging in to the server and running the command to check the database server status. For example, if you're using MySQL, you can run the command "service MYSQL status" to check the status of the MySQL service. To make your database server online, you need to log in to the SQL server management studio.
Afterward, go to the object explorer and right-click on the offline databases. A menu will open, and from the options click on bring online. The process will take a while and after some minutes your database server will become online. If your database server is online, but you are still experiencing issues, then check your database logs for any error messages or other issues that may be causing the "Error Establishing a Database Connection" message.
Checking whether your database server is offline is an important step in resolving the "Error Establishing a Database Connection" message in WordPress. If you are unable to resolve the issue on your own, it's recommended to contact your hosting provider's support team or a WordPress expert.
