What is the “Error establishing a database connection” in WordPress?

The “Error establishing a database connection” in WordPress is a message that appears on your website when WordPress is unable to connect to your website’s database. The database is where all your website’s content, including your posts, pages, and settings, are stored. Without a database connection, your website cannot function properly.

Causes of the “Error establishing a database connection”

Several factors can cause the error in WordPress. Here are some of the most common causes:

#1: Incorrect database credentials

WordPress needs correct database credentials to connect to your website’s database. If you have recently changed your database username, password, or database name, or if you have entered incorrect details during WordPress installation, you may encounter this error.

#2: Corrupted WordPress files

Sometimes, your WordPress files can get corrupted due to a malware infection or a failed WordPress update. Corrupted files can cause the database connection issue.

#3: Database server issues

Your database server can also cause the database connection issue. Your database server may be down, overloaded, or experiencing technical issues, preventing WordPress from connecting to the database.

Solutions to fix the “Error establishing a database connection”

Now that you know the causes of the Error let’s look at the solutions to fix it.

#1: Check your database credentials

The first step to fixing the “Error establishing a database connection” is to check your db credentials. You can do this by opening the wp-config.php file in your WordPress root directory and looking for the following lines:

define('DB_NAME', 'database_name_here');
define('DB_USER', 'username_here');
define('DB_PASSWORD', 'password_here');
define('DB_HOST', 'localhost');

Ensure that the database name, username, password, and host are correct. If you have recently changed your database credentials, update these details accordingly.
