How to Enable Joomla Error Reporting

Enable Error Reporting in Administrator

1. Sign in to Joomla Administrator.
2. Open System → Setup Panel → Global Configuration.
3. Open the Server tab.
4. Locate Error Reporting.
5. Select the level needed for the investigation. Maximum is appropriate when you deliberately need the broadest Joomla-managed PHP error reporting.
6. Save the configuration.

Reproduce the failure and capture useful evidence

Return to the exact page or action that fails. Record the complete error message, exception type, file and line, and relevant stack information. Do not publish credentials, tokens, database details, private filesystem paths, or other secrets in public support channels.

Understand what Joomla can and cannot control

Joomla's Error Reporting setting changes the PHP reporting level requested by the application, but hosting and PHP configuration can still determine whether errors are displayed, logged, redirected, or suppressed. If nothing appears on screen, inspect Joomla, PHP, and web-server logs instead of repeatedly increasing unrelated settings.

Use configuration.php only for recovery

If Administrator cannot load, the root configuration.php can be used for emergency configuration changes. Back up the file before editing, change only the error-reporting value required for diagnosis, and restore the intended production value afterward.

Restore the production setting

1. Capture the evidence you need.
2. Return to Global Configuration → Server.
3. Set Error Reporting back to the site's intended production value.
4. Save and retest the public page.

Error Reporting and Debug System are separate tools; do not leave either enabled more broadly than necessary.
