Enabling the built-in debugging feature in WordPress

WordPress includes a debug mode which helps reveal PHP problems.

To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

In order to enable the error logging to a file on the server you need to add yet one more similar line:

define( 'WP_DEBUG_LOG', true );

In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

define( 'WP_DEBUG_DISPLAY', true );

The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.

If you open wp-config.php and that define statement is not there, you can add it right before this line:

/* That's all, stop editing! Happy blogging. */

Please note that you’ll see everything, not only related to WPML. This will most likely include messages from other plugins, your theme and sometimes even WordPress core. The messages appear all over the place. Sometimes they appear right on top, but they can also appear in the middle of the page.
