How to enable WordPress debugging?

In this article, we will teach you how to enable debugging in WordPress, a vital skill for troubleshooting issues on your website. Here, we will discuss the steps required to activate debugging features, methods for debugging effectively, and how to view log files for deeper insights into errors.

How to Enable WordPress Debugging?

Enabling debugging in WordPress is straightforward. Follow these steps:

1. Access the wp-config.php File: Using an FTP client or your hosting provider’s file manager, locate and open the wp-config.php file in the root directory of your WordPress installation.
2. Modify the Debugging Constants: Look for the line that says /* That’s all, stop editing! Happy blogging. */. Above this line, add or modify the following lines:

   php
   define( ‘WP_DEBUG’, true ); define( ‘WP_DEBUG_LOG’, true ); define( ‘WP_DEBUG_DISPLAY’, false );

   • WP_DEBUG: This constant enables the debugging mode.
   • WP_DEBUG_LOG: This setting saves all errors to a debug.log file in the wp-content directory.
   • WP_DEBUG_DISPLAY: Set to false to prevent errors from displaying on the front end, which is useful for live sites.
3. Save the Changes: After editing, save the wp-config.php file and upload it back to your server if you’re using FTP.

To debug WordPress effectively, follow these methods:

• Check for PHP Errors: Once debugging is enabled, visit the pages where you suspect issues. If there are any PHP errors, they will be logged in the debug.log file located in the wp-content directory.
• Use Debugging Plugins: Consider installing debugging plugins like Query Monitor or Debug Bar. These plugins provide additional information, including queries, hooks, and PHP errors.
• Check Theme and Plugin Conflicts: Deactivate all plugins and switch to a default theme. Gradually reactivate them one by one to identify the source of the issue.

How Do I Enable Debugging?
