Step 1: Access Your WordPress Dashboard

First, log into your WordPress admin panel. You can do this by navigating to yourdomain.com/wp-admin and entering your username and password.

Step 2: Navigate to the Duplicator Plugin Settings

Once you are in the dashboard:

1. Look at the left-hand menu and find the Duplicator plugin.
2. Hover over the Duplicator plugin name and click on “Settings” from the dropdown menu.

Step 3: Access the Packages Settings

In the Settings section of the Duplicator plugin:

1. Click on the “Packages” tab. This tab controls various options related to how Duplicator creates packages for your site migration.

Step 4: Change the Archive Engine

Under the Packages tab, you will find an option for “SQL Script” By default, this is usually set to “mysqldump,” which can sometimes cause issues on certain hosts or larger databases.

1. Locate the “SQL Script” setting.
2. Change this setting from “mysqldump” to “PHP code.”

Step 5: Save Your Changes

After making the change:

1. Scroll down and click the “Save” button to apply the new settings.

Why This Fix Works

The “Host Build Interrupt” error often occurs because the mysqldump utility, which is typically used to create database backups, may not be supported by all hosting environments, especially those with limited resources or shared hosting plans. Switching to “PHP code” allows Duplicator to use PHP scripts to handle the database export, which is generally more compatible across different hosting environments.

Additional Tips

• Check PHP Limits: Ensure your PHP settings are optimized for large operations. Increasing limits for max_execution_time, memory_limit, and upload_max_filesize in your php.ini file can help avoid timeouts and memory issues.
• Disable Plugins: Sometimes, other active plugins can interfere with the backup process. Try temporarily deactivating non-essential plugins during the migration.
• Contact Hosting Support: If the problem persists, reach out to your hosting provider. They may offer additional insights or be able to adjust server settings to better accommodate your migration.

Conclusion

By following these steps, you should be able to fix the “Host Build Interrupt” error in the Duplicator plugin and successfully migrate your WordPress site. This straightforward adjustment to the archive engine from mysqldump to PHP code is an effective solution that enhances compatibility and reduces the chances of encountering build interruptions.
