Debugging mode in WordPress is a tool that developers use to find and fix errors or issues in a WordPress site. When debugging mode is enabled, WordPress will display detailed error messages and warnings that can help developers identify the source of the problem.
By default, debugging mode is disabled in WordPress to prevent users from seeing error messages that might confuse or scare them. However, when developers are working on a website, they may need to turn on debugging mode to see what is causing a problem or to test new code changes.
To enable debugging mode in WordPress, you can add the following line of code to your wp-config.php file:
Once you have added this line to your wp-config.php file and saved it, WordPress will start displaying error messages and warnings on the screen, as well as in the site’s error log files.
When debugging mode is enabled, developers can use tools like the WordPress debug log, which records all errors and warnings, to find and fix issues with their code. They can also use debugging tools like Xdebug, a PHP extension that provides advanced debugging features, to step through code and identify the source of an error.
It’s important to note that debugging mode should only be used by experienced developers who know how to interpret the error messages and fix the issues that they reveal. It is not recommended to leave debugging mode enabled on a production website as it can expose sensitive information to users and potential attackers.
