Undefined property?!

Hi @tschejoh

Thanks for reaching out, I’ll be happy to help!

Hi there,
?
Thanks for reaching out!
?
That message is a warning, not an error. PHP warnings and notices are nothing to worry about (Some of these can even be generated because the developer has to keep compatibility with older versions of WordPress as well as older PHP versions). You’re probably seeing that because of default WordPress behavior, but the good news is that it shouldn’t impact the functionality of your site. So you can simply disable it.
?
Please follow the instructions below.
?
1) Log into the Host Control Panel (Cpanel). Go to File Manager (or you can connect to FTP).
2) Get to the root directory of the website, open wp-config.php file.
3) In this file, you should search for:
?
define(‘WP_DEBUG’, false);
?
4) And insert this piece of code below:
?
ini_set(‘display_errors’,’Off’);
ini_set(‘error_reporting’, E_ALL );
define(‘WP_DEBUG’, false);
define(‘WP_DEBUG_DISPLAY’, false);
?
5) Save the file.

Thanks for your quick response and help. Worked. Br JL

Hi

I have the same problem, your solution is not working for me, maybe I did a mistake please guide me where to insert the code if my function.php look like this thanks:

/**

• For developers: WordPress debugging mode.
  *
• Change this to true to enable the display of notices during development.
• It is strongly recommended that plugin and theme developers use WP_DEBUG
• in their development environments.
  *
• For information on other constants that can be used for debugging,
• visit the Codex.

define( ‘WP_DEBUG’, false );
//define( ‘WP_DEBUG_DISPLAY’, false );
define( ‘WP_AUTO_UPDATE_CORE’, false );
/* That’s all, stop editing! Happy publishing. / /* Absolute path to the WordPress directory. / if ( ! defined( ‘ABSPATH’ ) ) { define( ‘ABSPATH’, dirname( FILE ) . ‘/’ ); } /* Sets up WordPress vars and included files. */

Hi @goldatlas

It doesn’t work because you didn’t add the code in the right PHP file. You added it in the functions.php, and it must be added in wp-config.php

To get to the wp-config.php file, you have to your host file explorer or connect to its FTP/SFTP. You’ll find the wp-config.php file at the root of your website files.

There is a warning that does not go away:

Warning: Undefined property: WP_Post_Type::$slug in app/public/wp-content/themes/lawfirm-child/archive-project.php on line 177

I tried to put this in wp-config.php
already:

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

It still shows the warning..
