# How to Fix Error Establishing a Database Connection in WordPress

"Error establishing a database connection" means WordPress cannot reach its database. It is a common error with a few clear causes. This guide explains how to diagnose and fix it.

## What the error means

WordPress stores your content in a MySQL database. If it cannot connect, usually because of wrong credentials, a database issue, or a server hiccup, it shows this error instead of your site.

## Step 1: Check your database credentials

Open *wp-config.php* and confirm the database name, username, password, and host (usually localhost) match what is in your hosting control panel. A recent migration or password change is the most common cause of a mismatch.

## Step 2: Confirm the database user's access

- In your control panel, make sure the database user is assigned to the database.
- Confirm the user has the right privileges.

## Step 3: Check the database itself

Open phpMyAdmin and confirm the database exists and has tables. Occasionally a database can need repair, which WordPress can attempt if you enable repair mode.

## Step 4: Rule out a server issue

If credentials are correct and it still fails, the database server may be temporarily overloaded or down. Wait a few minutes and retry, and check whether other sites on the account are affected.

## Troubleshooting summary

- **After a migration:** fix the credentials in wp-config.php.
- **Suddenly, no changes:** likely a temporary server issue; retry shortly.
- **Corrupt database:** try WordPress repair mode.
