Here’s how to troubleshoot and fix the issue. ### 1. **Check Database Credentials in** **`wp-config.php`** Start by verifying the credentials stored in your WordPress configuration file. - Login to cPanel. - Open **File Manager** under the **Files** section. - Navigate to your WordPress root directory (**usually** located in `/public_html/`). - Find and open the `wp-config.php` file for editing. Within the file, you’ll find entries like this: ``` define('DB_NAME', 'your_database_name'); define('DB_USER', 'your_database_user'); define('DB_PASSWORD', 'your_database_password'); define('DB_HOST', 'localhost'); ```   **Take note** of the following values: - `DB_NAME`: Your database name. - `DB_USER`: The MySQL username. - `DB_PASSWORD`: The password for that user. - `DB_HOST`: This is typically set to `localhost` unless your hosting provider uses a different hostname for databases. ### 2. **Verify Database Details in cPanel** Now that you’ve noted the database credentials from `wp-config.php`, you need to confirm that they match your actual database details. - In cPanel, go to **MySQL Databases** under the **Databases** section. - Look for the **Current Databases** section. - Verify that the `DB_NAME` from `wp-config.php` matches an existing database in this list. - Check that the **User** assigned to this database matches the `DB_USER` in `wp-config.php`. If any of these details don’t match, you’ll need to update them in the `wp-config.php` file to reflect the correct database name and username.   ### 3. **Reset the MySQL User Password** If the database details are correct, the issue might be with the database password. You can reset the MySQL user’s password and update it in `wp-config.php`. **Steps:** - In cPanel, go to **MySQL Databases**. - Scroll down to the **Current Users** section. - Find the MySQL user matching the `DB_USER` value in `wp-config.php`. - Click **Change Password** next to the user and enter a new, strong password. Now, update the `DB_PASSWORD` in your `wp-config.php` file with the new password: ``` define('DB_PASSWORD', 'new_password_here'); ```   Save the changes in the file.   ### 4. **Ensure MySQL User Has Proper Permissions** The MySQL user needs the correct permissions to interact with the database. If the permissions are incorrect, the connection will fail. **Steps:** - In cPanel, under **MySQL Databases**, scroll to the **Add User to Database** section. - Select the correct MySQL **User** and **Database** from the dropdown menus. - Click **Add**. - On the next screen, ensure **All Privileges** are selected, then click **Make Changes**. This grants the MySQL user full access to the database, ensuring proper functionality. - [Getting Started](https://help.blakemarkdigital.co.uk/getting-started) - [Web Hosting](https://help.blakemarkdigital.co.uk/web-hosting#main-content) - [Elementor](https://help.blakemarkdigital.co.uk/web-hosting#elementor) - [WordPress](https://help.blakemarkdigital.co.uk/web-hosting#wordpress) - [Security](https://help.blakemarkdigital.co.uk/web-hosting#security) - [Email](https://help.blakemarkdigital.co.uk/email#main-content) - [Mail Clients](https://help.blakemarkdigital.co.uk/email#mail-clients) - [SpamExperts](https://help.blakemarkdigital.co.uk/email#spamexperts) - [MailChannels](https://help.blakemarkdigital.co.uk/email#mailchannels) - [Domains](https://help.blakemarkdigital.co.uk/domains#main-content) - [Domain Privacy](https://help.blakemarkdigital.co.uk/domains#domain-privacy) - [Billing](https://help.blakemarkdigital.co.uk/billing) - [cPanel](https://help.blakemarkdigital.co.uk/cpanel#main-content) - [JetBackup](https://help.blakemarkdigital.co.uk/cpanel#jetbackup) - [Softaculous](https://help.blakemarkdigital.co.uk/cpanel#softaculous) - [WordPress Glossary Terms](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#main-content) - [H](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#h) [![Blake Mark Digital Logo](https://help.blakemarkdigital.co.uk/hs-fs/hubfs/Asset%205.png?width=250&height=71&name=Asset%205.png "Blake Mark Digital Logo")](https://blakemarkdigital.co.uk/) Blake Mark Digital is a digital marketing agency supporting SMEs and non-profits with strategic branding, content, and campaigns that drive real results 124-128 City Road, London, EC1V 2NX [support@blakemarkdigital.co.uk](mailto:support@blakemarkdigital.co.uk) +44 20 4578 9582 [mailto:support@blakemarkproductions.com](mailto:support@blakemarkproductions.com) Copyright © Blake Mark Productions Ltd
