How To Turn On Debug Messages For WordPress

This simple thing will help you find the best solution for getting rid of the most WordPress errors. I already mentioned above the “WordPress debug” feature. Below I will make a special section about it.

By default, WordPress will turn off all debugging messages so the visitor to the site can’t see any error messages showing anything wrong with the code.

If you do any WordPress development, such as new plugins or theme development, this can cause a problem as you won’t see if you have any settings wrongs.

Turning on debug mode will display all warnings or error messages you have with any installed plugins or themes. The “WordPress debug” feature makes it easy to spot outdated or use old WordPress functions that are not supported anymore.

Turn On Debugging

To turn on debug messages you need to open up your wp-config.php file and find the line.

define('WP_DEBUG', false);

Comment out this line a replace it with.

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

Please Note

You must remember to turn this off when you put your website live or the visitor will be able to see all your debugging messages.
