Don’t worry, though, because I’m here to help you troubleshoot and resolve this problem once and for all!

Before we dive into the troubleshooting process, let’s briefly understand what the WordPress database is and why it’s crucial for your website’s functionality. The WordPress database is where all your website’s data is stored, including blog posts, pages, comments, and settings. It’s like the backbone of your site, ensuring that everything runs smoothly.

Now, let’s jump right into the action and explore the steps to diagnose and fix the WordPress database error on 000webhost.

Common Causes of WordPress Database Error on 000webhost

Understanding the root causes of the database error is the first step towards resolving it. Here are some common culprits behind this pesky issue:

  1. Incorrect Database Credentials: One of the main reasons for the database error is incorrect database login details. This can happen when you change your hosting provider or migrate your site to a different server. Double-check your database name, username, password, and host details to ensure they are accurate.

  2. Corrupted Database Files: Over time, database files can become corrupted due to various reasons, such as server crashes, incomplete updates, or incompatible plugins/themes. Corrupted files can lead to database errors, so it’s essential to identify and repair them.

  3. Insufficient Database Permissions: Sometimes, the database user assigned to your WordPress site might not have sufficient privileges to perform essential tasks. This can result in a database error, preventing your site from functioning correctly.

Now that we have a good grasp of the potential causes, let’s move on to the troubleshooting steps!

Troubleshooting WordPress Database Error on 000webhost

In this section, I’ll guide you through a step-by-step troubleshooting process to help you resolve the database error on 000webhost. Let’s get started:

Step 1: Verify Database Credentials

The first thing you should do is double-check your database credentials. Follow these steps:

  1. Login to your 000webhost account and navigate to the MySQL Databases section.
  2. Make sure the database name, username, password, and host details match the ones specified in your WordPress configuration file (wp-config.php).
  3. If you’ve recently migrated your site, ensure that the database details are updated accordingly.

Step 2: Repair Corrupted Database Tables

If the database credentials are correct, the next possible culprit could be corrupted database tables. To repair them, follow these steps:

  1. Access your website’s files using an FTP client or the 000webhost file manager.

  2. Locate the wp-config.php file and add the following line just before the "That’s all, stop editing!" comment:

    define('WP_ALLOW_REPAIR', true);

    Save the file and upload it back to your server.

  3. Open your web browser and visit the following URL (replace ‘’ with your actual domain):

    This will take you to the WordPress database repair page. Click on the "Repair Database" button to initiate the repair process.

Step 3: Check Plugin and Theme Compatibility

If the above steps didn’t resolve the issue, it’s time to investigate plugins and themes. Follow these steps:

  1. Access your website’s files again and navigate to the "wp-content" directory.

  2. Rename the "plugins" folder to something like "plugins_deactivated". This will deactivate all your plugins temporarily.

  3. Check if the database error persists. If it’s resolved, one of the plugins was causing the issue.

    To identify the problematic plugin, revert the folder name back to "plugins" and activate the plugins one by one. After activating each plugin, refresh your site and check if the database error reappears. Repeat this process until you find the culprit.

  4. If plugins are not the cause, repeat step 2 and rename the "themes" folder to "themes_deactivated". This will deactivate your current theme.

  5. Check if the error is resolved. If so, it means your theme was causing the issue. Reach out to the theme developer for assistance or consider switching to a different theme.


Phew! We made it through the troubleshooting process for the WordPress database error on 000webhost. By following the steps outlined in this guide, you should be able to resolve the issue and get your website back up and running smoothly.
