Identifying and Fixing Common WordPress Errors with WP_Debug

WP_Debug is a debugging mode that can be enabled in WordPress to display error messages and other debugging information. Here are some of the most common WordPress errors that can be detected and solved using WP_Debug.

1. White Screen of Death (WSOD)

The White Screen of Death (WSOD) is a common WordPress error that occurs when there's a PHP error in your website's code. When this happens, your website's pages will display a blank white screen, making it impossible to access your website. With WP_Debug, you can enable error reporting and identify the cause of the issue, such as a problematic plugin or theme.

How to Fix:

  • Enable WP_Debug by adding the following code to your website's wp-config.php file:

define('WP_DEBUG', true);

define('WP_DEBUG_LOG', true);

define('WP_DEBUG_DISPLAY', false);
  • Reload your website to generate an error log file in the wp-content directory.

  • Access the log file to identify the cause of the error, which could be a problematic plugin or theme.

  • Disable the problematic Plugin or Theme, and your website should work correctly.

2. Plugin Conflicts

Plugins are a great way to add functionality to your website, but sometimes they can conflict with each other, causing issues. WP_Debug can help identify which plugins are causing conflicts by displaying error messages and debugging information.

How to Fix

  • Enable WP_Debug by adding the code shown in point 1 above.

  • Access your website to generate the error log file.

  • Check the error log file to identify the conflicting plugins.

  • Disable the conflicting plugins, and your website should function correctly.

3. Database Connection Errors

WordPress stores all of its content in a database, so any issues with the database can cause problems with your website. If you're experiencing database connection errors, WP_Debug can help you identify the issue by displaying error messages and debugging information.

How to Fix

  • Enable WP_Debug by adding the code shown in point 1 above.

  • Access your website to generate the error log file and check the error log file to identify the cause of the database connection error.

  • Check if the issue is due to incorrect login credentials or a server issue.

  • Correct the issue by updating the login credentials or contacting your hosting provider.

4. Syntax Errors

Syntax errors occur when there's an error in your code syntax. These errors can cause your website to display error messages or not load at all. WP_Debug can help identify syntax errors by displaying the exact line of code causing the issue.

How to Fix:

  • Enable WP_Debug by adding the code shown in point 1 above.

  • Access your website to generate the error log file.

  • Check the error log file to identify the line of code causing the syntax error.

  • Correct the line of code, and your website should function correctly.

5. Memory Limit Errors

WordPress requires a certain amount of memory to run correctly. If your website's memory limit is exceeded, you may experience memory limit errors. WP_Debug can help identify memory limit errors by displaying error messages and debugging information.

How to Fix:

  • Enable WP_Debug by adding the code shown in point 1 above.

  • Access your website to generate the error log file.

  • Check the error log file to identify the cause of the memory limit error, which could be due to a problematic plugin or theme or insufficient server memory.

  • Correct the issue by disabling the problematic plugin or theme or contacting your hosting provider to increase the memory limit.

General Tips for Troubleshooting WordPress Errors

  • Keep your WordPress installation, Themes, and Plugins up to date to minimize the risk of encountering errors.

  • Regularly back up your site to ensure you have a working version to revert to in case of issues.

  • Use a staging environment to test updates and changes before applying them to your live site.

  • Make use of error logs, which can be accessed via your hosting account, to gain more information about issues.

  • Familiarize yourself with the WordPress Codex and official documentation for plugins and themes you use, as they can provide valuable troubleshooting information.
