Why WordPress Debugging Matters for Your Website?

WordPress debugging involves maintaining a high-performing, secure website that creates excellent user experiences.

Common WordPress issues that need debugging include:

  • Plugin and Theme Conflicts: Affects most WordPress sites. These conflicts often manifest as:

    1. Broken functionality after plugin updates
    2. Layout issues when themes clash with plugins
    3. JavaScript errors preventing interactive elements from working
    4. Database queries that slow down your entire site
  • White Screen of Death (WSOD): Occurs due to PHP errors/memory limit exhaustion. These issues often lead to a fatal plugin conflict, causing your site to crash.

  • Performance Bottlenecks: Causes slow loading times/excessive database queries/unoptimized images. These issues can destroy both the user experience/SEO performance.

  • Post-migration Errors: Affects websites moving between hosting providers. Database connection issues, incorrect file paths, and URL mismatches can leave sites non-functional.

The Cost of Unresolved WordPress Errors

4 Steps to Set Up wp_debug in CloudPanel

Step 1: Access Your WordPress Files on MGT.io

Method 1: CloudPanel File Manager

  1. Log in to your MGT.io account and access CloudPanel.
  2. Go to your site's management dashboard.
  3. Click "File Manager" from the main menu.
  4. Browse to your WordPress root directory (e.g., public_html).

Method 2: FTP Access (Advanced Users)

advanced users accessing wordpress files via ftp for secure debug configuration in cloudpanel

If you prefer traditional FTP clients like 'FileZilla':

  1. Retrieve FTP credentials from CloudPanel's "FTP" section.
  2. Connect using your 'preferred FTP client'.
  3. Go to the' WordPress installation directory'.

Note: Always create a backup before changing core files. MGT.io's “hourly snapshots” provide automatic protection. Manual backups enable you to revert changes if necessary.

Step 2: Configure wp-config.php for Debug Mode

  1. Locate the 'wp-config.php' file in your WordPress root directory. This sensitive file controls the core configuration settings of your site.
  2. Find the right location for 'debug settings' & look for the comment line specifying:

/* That's all, stop editing! Happy publishing. */

  1. Add these debug configuration lines before the above comment:

// Enable WordPress debugging

define('WP_DEBUG', true);

define('WP_DEBUG_LOG', true);

define('WP_DEBUG_DISPLAY', false);

@ini_set('display_errors', 0);

Note:

  • WP_DEBUG: Turns on WordPress's 'debug mode' to capture errors.
  • WP_DEBUG_LOG: Saves all errors to a log file for later review.
  • WP_DEBUG_DISPLAY: Stops errors from showing on your live site.
  • @ini_set('display_errors', 0): Extra protection against public error display.

Step 3: Read the Debug Log Output

Once debug mode is active, WordPress creates a 'debug.log' file in your wp-content directory. This file contains detailed error information, like:

  • Fatal errors: Code problems that crash your site.
  • Warnings: Issues that don't break functionality but show problems.
  • Notices: Minor issues that might cause future problems.
  • Deprecated function calls: Code using outdated WordPress functions.

Note: CloudPanel log access makes reviewing these logs simple. You don't need to download files via FTP. Access logs through the CloudPanel interface by navigating to Logs > Application Logs.

Step 4: Safety Best Practices

While MGT.io provides automatic hourly snapshots, create a manual backup before debugging. It allows you to restore your site in the event of an issue, ensuring data integrity and reliability.

Seek the platform's guided support:

  • If you're uncomfortable editing core files.
  • When errors seem server-related rather than WordPress-specific.
  • If debugging reveals concerns.
  • When performance issues need server-level changes.

MGT.io's support team can guide you through complex debugging scenarios. They can also assist with handling server-side configurations that need root access.
