Logs

The Logs Viewing feature provides users with a centralised interface to monitor and troubleshoot their site using various server and application logs. It supports both Nginx and OpenLiteSpeed environments and includes logs specific to PHP, WordPress, and server-level events.

Accessing the Logs Viewer

1. Navigate to the FlyWP dashboard and select the desired site.
2. Click on the “Logs” option in the left sidebar. By default, this will show the debug.log of the selected WordPress site.

Supported Logs by Site Type

FlyWP supports both OpenLiteSpeed and NGINX sites, both of which have different log files. And for these sites, FlyWP supports viewing these logs.

🔹 Nginx

  • Nginx Access Log (access.log)
  • Nginx Error Log (error.log)
  • PHP Error Log (error.log)
  • WordPress Debug Log (debug/debug.log)

🔹 OpenLiteSpeed

  • Access Log (access.log)
  • Error Log (error.log)
  • LS Restart Log (lsrestart.log)
  • Stderr Log (stderr.log)
  • WordPress Debug Log (debug/debug.log)

Viewing Logs

Logs are displayed with:

  • Clear timestamps
  • Scrollable view for larger logs.

Understanding Log Entries

Each log entry includes:

  • Timestamp: When the event occurred.
  • Type: Log level (notice, warning, error, deprecated).
  • Description: Details about the issue and possible source (plugin, theme, or core).

Common Log Types

  • Deprecated: Outdated PHP function, safe to ignore but updates are recommended.
  • Warning: Non-critical issue, doesn’t stop any core function but should be fixed.
  • Notice: Minor alerts for developers; low priority.
  • Error: Critical issue; stops execution and must be resolved immediately.

Security and Privacy Considerations

  • Log entries are read-only.
  • Logs are only available to authorised users.
  • Log retention may be subject to server policy (e.g., logs older than 30 days are auto-purged).

Configuration and Setup

Enabling the WordPress Debug Log

You can enable the WordPress debug log using either the UI or manual file editing.

Option 1: Using the WP-CONFIG Page (Recommended)

  • Go to: Site Tools → WP-CONFIG
  • Toggle WP Debug Mode to Enable
  • And click on save. Now you should be able to view the WordPress debug log.

Logging Best Practices for High-Traffic and Production Sites

If your website experiences high traffic or is running in a live production environment, it’s important to be cautious with logging—especially with WordPress and Nginx logs.

  • WordPress debug logging (wp-content/debug.log) should be disabled in production unless you’re actively troubleshooting. Continuous logging can introduce performance overhead and may slow down your site.
  • Nginx logs, particularly the access log, can grow rapidly on high-traffic sites. Every request is recorded, which can quickly lead to large files that consume disc space and impact server performance.

To maintain optimal performance, always resolve critical issues first, then disable or limit logging where appropriate in a production environment. 

Troubleshooting

IssueSolution
Logs not displayingCheck file permissions and server log path configuration.
Permission denied errorEnsure the user has access rights; check file ownership on the server.
No WordPress Debug logEnsure Debug Mode is enabled in WP-Config Page. If you still face the same error, try checking the PHP error logs.
Logs missing entriesVerify server log level settings or that logging is not disabled.

FAQs

Q: Can I view logs older than 7 days?
A: As long as you do not clean the logs, you can always find the logs.

Q: How frequently are logs updated?
A: Logs are not updated. To get the latest logs, click on the refresh icon.

Q: Can I share logs securely with support?
A: Yes, download logs and share them manually. Avoid sharing publicly due to sensitive data.
