Troubleshooting Matomo Errors

Identifying the root cause of a Matomo error in WordPress is the first step toward resolving it. Here’s a step-by-step guide to help you troubleshoot these issues effectively.

Step-by-Step Guide to Identifying the Root Cause

Check for Error Messages:
- Look at any error messages displayed on your Matomo dashboard or WordPress admin panel. These messages often provide clues about what’s going wrong.
Review Matomo Logs:
- Matomo generates logs that can help diagnose problems. Access the Matomo error logs via your server’s file manager or Matomo’s settings to see detailed error reports.
Examine Your Server Logs:
- Check your server logs (e.g., Apache or Nginx logs) for any related error messages. These logs can provide additional context about server-side issues affecting Matomo.
Check Database Health:
- Verify that your WordPress database is functioning correctly. Use tools like phpMyAdmin to check for any database errors or issues with Matomo tables.
Inspect Plugin and Theme Conflicts:
- Disable other plugins and switch to a default WordPress theme (e.g., Twenty Twenty-One) to see if the issue persists. If Matomo works correctly, a plugin or theme conflict is likely the cause.
Review Recent Changes:
- Consider any recent changes you’ve made to your WordPress site, such as new plugins, theme updates, or custom code. Reverting these changes can help identify the source of the problem.

Tools and Methods for Diagnosing Issues

[log]
log_writers[] = "file"
log_level = "DEBUG"

Browser Developer Tools:
- Use your browser’s developer tools (F12 or right-click > Inspect) to check for JavaScript errors and network issues. The console and network tabs can reveal problems with Matomo tracking scripts.
Online Forums and Documentation:
- Visit the Matomo community forums and read through the documentation for troubleshooting tips. Other users may have encountered and solved similar issues.

By following these steps and using these tools, you can pinpoint the cause of the Matomo error in WordPress and take appropriate action to resolve it.
