Seeing this error message on your WordPress site can be nerve-wracking, but fear not! It simply means your website can’t connect to its data storage like a library losing its card catalog. This often occurs due to:

Verify Credentials: Ensure the following values match your database settings:

• DB_NAME: Database name
• DB_USER: Database username
• DB_PASSWORD: Database password
• DB_HOST: Database hostname (usually localhost)

Enter the correct username, password, database name & host then it will be fixed. This is the most effective solution for the error of establishing a database connection.

How to find the DB name, DB username, and password?
