How to set debug in wp-config.php?


Hi All,

@rahul286 @virtubox

Multisite was setup with EE,



I think there are two ways to show error or debug logs:

1# The first way: debug.log is generated by EE debug commend to enable/disable debug as tutorial shows:

But how to limit the size of the debug log file please?

2# Seoncd way:

In wp-config.php, define(‘WP_DEBUG_DISPLAY’, false) was defined as false, the debug error will show up AT FRONTEND.

For me, I use the following lines:

define( ‘WP_DEBUG’, true );

define( ‘WP_DEBUG_LOG’, true );

define( ‘WP_DEBUG_DISPLAY’, false );

what make me quite confused is the debug errors will keep showing up at frontend, please check the screenshot:

I mean this line(define( ‘WP_DEBUG_DISPLAY’, false ):wink: seems not working as expected.

How to make it work please?

and how to set the directory to store access.log and error.log please?




the proper config to set in your wp-config.php seems to be :

 // Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings 
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );

according to the WP CODEX


Hi @virtubox,@rahul286

I tested but the same issue:

does EE only recommend to enable debug function by EE debug commend line?


@alexlii – The debug details as seen here are not related to the WordPress debugging functionality as shown in the WordPress Codex.

ee debug [Options]
Options :
    	-i                              # Interactive debug
      	--nginx                         # Debug Nginx
       	--rewrite                       # Debug Nginx rewrite rules
       	--fpm                           # Debug FastCGI
        --fpm7                          # Debug FastCGI PHP 7.0
       	--php                           # Debug PHP
        --php7                          # Debug PHP 7.0
       	--mysql                         # Debug MySQL
       	--import-slow-log-interval      # Import MySQL slow log to Anemometer
       	--all                           # Debug all server paramenters

These are for debugging NGINX, PHP-FPM, and slow MySQL queries.

I’m not sure what your question really is, hopefully this helps though.


@brianjking thanks.

does that mean the following debug setting will be invalid please?

define( ‘WP_DEBUG_DISPLAY’, false );
