WordPress has a special debug mode that can be used to log error messages of the server-side scripting language PHP, in which much of the WordPress logic is programmed.<\/p>\n

By default the mode is not activated and this is a fine, because it should only be switched on for troubleshooting and then switched off again.<\/p>\n

Activating the Debug Mode<\/h2>\n

To activate the debug mode, open your configuration file wp-config.php<\/code> in the root directory of your site in a text editor. Scroll down to this line:<\/p>\n

\n
define('WP_DEBUG', false);<\/pre>\n<\/div>\n
The false<\/code>\u00a0means that the mode is not activated.<\/p>\n
Replace this line with the following:<\/p>\n
define('WP_DEBUG', true);\r\ndefine('WP_DEBUG_LOG', true);\r\ndefine('WP_DEBUG_DISPLAY', false);<\/pre>\n
Explanation<\/h3>\n
WP_DEBUG<\/code><\/p>\n
Setting this to true<\/code> switches the mode on in general. Important in this context are the two new values.<\/p>\n
WP_DEBUG_LOG<\/code><\/p>\n
If set to true<\/code>, WP_DEBUG_LOG<\/code> ensures that any error messages that occur are logged in a server-side file<\/strong>. The file is created in the wp-content<\/code>\u00a0directory of your site with the default name debug.log<\/code>. So make sure that this directory is writable for the PHP process or create the file manually and give it write permission (664).<\/p>\n
WP_DEBUG_DISPLAY<\/code><\/p>\n
For a productive site<\/strong> it is very important<\/strong> to set the third value WP_DEBUG_DISPLAY<\/code> to false<\/code>, because it ensures that the error messages are not displayed in the frontend<\/strong> of your site.<\/p>\n
\n
Deactivating the Debug Mode<\/h2>\n
When the debugging is finished, it is important to switch off the debug mode again. Otherwise the log file would continue to be bloated with unnecessary entries.<\/p>\n
To switch off the WordPress debug mode, set the value WP_DEBUG<\/code> back to false<\/code>\u00a0as in the initial state.<\/p>\n
define('WP_DEBUG', false);<\/pre>\n<\/div>\n
