Edit your wp-config.php file, located in WordPress root folder, and add or replace define('WP_DEBUG', true);

In this way WordPress will print the logs on the screen. This may be very annoying, so you would like to redirect all logs in a file.

ini_set('display_errors', 0 );
 
// By default, WordPress write the logs in /wp-content/log/debug.log
// comment out the line below to change path and log filename
//ini_set( 'error_log', '/path/site.com/wp-content/logs/debug.log' );
