Duplicator Migration Failed? Troubleshooting Common Issues
Duplicator is a powerful WordPress plugin for migrating or backing up your website. However, occasionally, the migration process can fail. Don't panic! Most issues are easily resolvable with a systematic approach. This guide outlines common causes and solutions.
Diagnosing the Problem
The first step is understanding why the migration failed. The Duplicator installer log file, typically located in the destination directory (e.g., `installer-backup.php.log`), is your best friend. Examine it for error messages. Common error codes and their meanings include:
- Timeout Errors (500, 504): These often indicate server limitations. The migration process exceeded the server's PHP execution time limit (typically 30-60 seconds).
- Database Connection Errors: Issues with database credentials (host, username, password, database name) provided during the installer process.
- File Size Limits: Server restrictions on the maximum file upload size.
- Missing Files/Permissions: Problems with file permissions or missing files in the archive.
Fixing Common Duplicator Migration Failures
Once you've identified the error, apply these fixes:
- Increase PHP Limits: Contact your hosting provider to increase `max_execution_time`, `memory_limit`, and `upload_max_filesize` in your `php.ini` file or through your hosting control panel. For example, try setting `max_execution_time` to 300 seconds and `memory_limit` to 256M.
- Verify Database Credentials: Double-check the database host, username, password, and database name you entered during the installer process. Ensure the database exists and the user has appropriate privileges (read/write).
- Address File Size Limits: If the archive is too large, try creating a smaller archive by excluding unnecessary files (e.g., large media files, plugin backups) in the Duplicator package settings. Alternatively, explore using Duplicator Pro for its enhanced large archive handling capabilities.
- Check File Permissions: Ensure the web server user has appropriate read and write permissions to the destination directory. A common setting is 755 for directories and 644 for files.
- Retry the Migration: After implementing the necessary fixes, retry the migration. If the issue persists, carefully review the installer log file again for new error messages.
If you're still facing issues, consider reaching out to Duplicator's support team or consult WordPress community forums for assistance. Providing detailed error messages from the log file will greatly help in troubleshooting.
