Is your WordPress website displaying an “Error establishing a database connection” message? It is a fatal mistake that prevents people from accessing your WordPress website.

When WordPress is unable to connect to the database, this error occurs. A variety of factors might disrupt your WordPress database connection, making it tough for beginners to resolve.

In this post, we’ll teach you how to simply solve the issue and Easy Solution Provided by IT Company Database Services.

What Causes Error Establishing a Database Connection in WordPress? 

The ‘Error establishing a database connection’ might be caused by inaccurate database information in your WordPress settings, a faulty database, or an unresponsive database server.

A database is a piece of software that allows you to easily store, organize, and retrieve data into other pieces of software.

WordPress, being a content management system, stores all of your website’s content and data in a database. Each time someone visits your website, it connects to the database.

WordPress needs the following information in order to connect to the database:

  • The name of the database
  • Username in the database
  • Password for the database
  • The database server

This data is saved in your WordPress configuration file, wp-config.php.

If any of these elements is wrong, WordPress will be unable to connect to your database server and will display the ‘message establishing a database connection’ message.

One of the most prevalent WordPress mistakes. In addition to invalid credentials, this error can occur if the database server is unavailable or the database files are faulty.

Let’s look at how to troubleshoot the error establishing database connection in WordPress step by step.

1. Verify the WordPress Database Credentials

Incorrect database credentials are the most prevalent cause of database connection errors in WordPress. This might be the most likely cause if you just switched your WordPress site to a new host.

The wp-config.php file contains your WordPress database credentials. The WordPress configuration file provides critical WordPress settings, including database information.

If you’ve never modified the wp-config.php file before, see our instruction on how to modify the wp-config.php file in WordPress.

In the wp-config.php file, check for the following lines.

1. // ** MySQL settings - obtain these information from your web host ** // 

2. /** The database name for WordPress */ 

3. define('DB_NAME,' 'database_name_here'); 

4. /** MySQL database login */ 

5. DB_USER = define('username_here'); 

6. /** Password for MySQL database */ 

7. define('DB_PASSWORD,' 'password_here'); 

8. */ MySQL hostname 

DB_HOST = define('localhost'); 

You must ensure that the database name, username, password, and database host are all accurate.

You may validate this information from the dashboard of your WordPress hosting account. Simply log in to your hosting account and navigate to the database area, where you will see MySQL databases.

In this example, we’re utilizing the DirectAdmin dashboard, but the procedure would be comparable in other hosting control panels.

This will send you to your hosting dashboard’s database management page. You may get your database name and username from here.

Below that are the database users, as well as links to alter the user password.

Once you’ve checked your database name, username, and password, you may modify them in your wp-config.php file if necessary.

After that, try viewing your website again to check whether the database connection problem has gone away.

If you can still see the error, it suggests that something else is incorrect. Continue reading for further troubleshooting tips.

2. Verify the Database Host Information

If you are certain that your database name, username, and password are accurate, you should double-check that you are using the correct database host information.

To validate your Database Services, contact your WordPress hosting company.

3. Restore the WordPress database

If you see a different error message in the wp-admin, such as “One or more database tables are inaccessible. If the database requires repair, you must repair it.

You may accomplish this by inserting the following code into your wp-config.php file. Make sure it’s right before ‘That’s all, quit editing!’ wp-config.php’s line wp-config.php.

  1. define(true, ‘WP_ALLOW_REPAIR’);

4. Determine if your Database server is Offline

If everything appears to be in order but WordPress is still unable to connect to the database, your database server (MySQL server) may be unavailable.

This might occur as a result of high server traffic. Simply said, your host server cannot manage the demand (particularly if you are using shared hosting).

Your website will become extremely sluggish, and some users may see an error. So, the best thing you can do is call or chat with your hosting provider and inquire if your MySQL server is responsive.

If you are able to connect, we must determine whether your database user has necessary permissions. Make a new file named testconnection.php and add the following code into it:

1. <?php 

2. $link = mysqli_connect('localhost', 'username', 'password'); 

3. if (!$link) { 

die('Could not connect: ' . mysqli_error()); 

} 

4. echo 'Connected successfully'; 

5. mysqli_close($link); 

?>
