Update WordPress database connection string
If your WordPress site is out of sync with your database and displays the following error: "Error Connecting to the Database", you'll need to update the connection strings on your WordPress site.
- You should always backup your site before performing any troubleshooting.
- Locate your database details. (
cPanel / Plesk / Web Hosting / Managed WordPress).
- Edit the wp-config.php for your website. (
cPanel / Plesk / Web Hosting / Managed WordPress / VPS)
- In wp-config.php file, locate the section that looks like this example:
/** The name of the database for WordPress */ define('DB_NAME', 'yourdatabasename'); /** MySQL database username */ define('DB_USER', 'yourusername'); /** MySQL database password */ define('DB_PASSWORD', 'yourpassword'); /** MySQL hostname */ define('DB_HOST', 'yourhostname'); $table_prefix = 'yourtableprefix';
- Confirm the information in this file matches the database details you found earlier.
- Replace yourdatabasename with your MySQL Database Name
- Replace yourusername with your MySQL User Name
- Replace yourpassword with your MySQL password
- Replace yourhostname with your MySQL Host Name
- Replace yourtableprefix with your Table Prefix
- If any of the information in the wp-config.php file doesn't match your database details, then update the file with the correct information.
- Save the updated file.
- Check your website to verify it's back online.
