Question

Hi, I have a WordPress site and because it is old (very old!) how can I hide PHP errors?

For example here are some of the errors:

• The submenus are not showing because of some Walker class.
• The styles are gone! Instead of showing Areal as a font a Times New Roman is displayed.

Here are the errors I am getting (btw - I cannot get into the admin dashboard because of them!):

I know that in the wp-config.php in the root of the site there is a line of code:

define('WP_DEBUG', false);

but how can I edit it?

Thanks!

Answer 1

To totally hide the PHP errors in wp-config.php you must replace:

define('WP_DEBUG', false);

with:

ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

Answer 2

You can also debug the errors in your WordPress system;

For this purpose, you can add these line of code in wp-config.php:

Replace:

define('WP_DEBUG', false);

WITH (you can also read the comments in the code):

define('WP_DEBUG', true);
//Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
//false == Showing errors ONLY in /wp-content/debug.log file NOT in the site
define('WP_DEBUG_DISPLAY', true);

You can also watch this useful video about debugging WordPress sites:

Or you can use some debugging WP plugins: read more here
