Disable Debug Mode

What This Does 
 This protection ensures that WordPress debug mode is disabled in production environments. 
 It prevents error messages and diagnostic information from being displayed publicly. 
 
 Why It Matters 
 When debug mode is enabled, WordPress may display: 
 
 PHP errors and warnings 
 file paths and system structure 
 plugin and theme information 
 database query details 
 
 This information can expose sensitive details about your site and make it easier for attackers to identify vulnerabilities. 
 
 When to Apply It 
 This protection is recommended for all production websites. 
 Apply it when: 
 
 your site is publicly accessible 
 development is complete 
 you want to prevent information leakage 
 
 
 When Not to Apply It 
 You may choose not to apply this protection if: 
 
 you are actively developing or debugging your site 
 you require visible error output for troubleshooting 
 
 In these cases, debug mode should only be enabled temporarily and never on a live site. 
 
 How Steel Security Applies This 
 Steel Security ensures debug settings are configured securely. 
 This typically involves: 
 
 disabling WP_DEBUG 
 preventing error display in the browser 
 ensuring errors are not publicly exposed 
 
 Changes are applied directly to your WordPress configuration. 
 
 What to Expect After Applying 
 After applying this protection: 
 
 errors will no longer be displayed publicly 
 your site will appear cleaner and more stable to users 
 sensitive debugging information will be hidden 
 
 This does not prevent errors from occurring — it only prevents exposure. 
 
 How to Verify 
 To verify the protection: 
 
 Trigger or observe an error on your site (if applicable) 
 Confirm that error details are not displayed publicly 
 
 You should not see: 
 
 PHP warnings 
 file paths 
 stack traces 
 
 
 How to Revert (Rollback) 
 To revert this protection: 
 
 Navigate to the hardening section in Steel Security 
 Disable the control 
 Confirm the change 
 Verify that debug output is restored (if needed) 
 
 Only enable debug mode temporarily and with caution. 
 
 Common Issues 
 Errors Are No Longer Visible 
 This is expected. 
 Debug output is being hidden for security. 
 If needed: 
 
 enable logging instead of display 
 review server logs for diagnostics 
 
 
 Changes Do Not Take Effect 
 
 confirm configuration was updated correctly 
 check for conflicting settings in wp-config.php 
 ensure hosting environment is not overriding values
