What does WordPress Debug Mode Reveal about Site Errors?

When we activate WordPress debug mode, it acts as a master switch that reveals PHP errors, warnings, and notices that are typically hidden from view. By configuring specific constants in the `wp-config.php` file, we can uncover various levels of technical issues:

• PHP Fatal Errors: These are critical issues, such as out-of-memory errors, that stop a script from executing and can break your site.
• PHP Warnings: These indicate that something is wrong, such as a missing file that failed to load, which might break partial functionality without crashing the entire site.
• PHP Notices: These reveal minor issues like undefined variables. While non-fatal, addressing them is a prerequisite for maintaining high code quality and site stability.
• Deprecated Function Calls: These signal that a plugin or theme is using outdated code that is slated for removal in future versions of PHP or WordPress.
• Database Errors: Debug mode can pinpoint conflicts where specific tables cannot be found, often pointing to plugin or theme issues.

To manage this data securely, we recommend using WP_DEBUG_LOG to capture these details in a private file (`/wp-content/debug.log`) while setting WP_DEBUG_DISPLAY to false. This prevents sensitive file paths or database details from being exposed to your visitors.
