PHP warnings and notices are not like internal server error, syntax errors, or fatal errors, which stop your website from loading.
They are nothing to worry about on a production site most of the time.
Though the plugin/theme developer should know about these so that they may fix them in a future release.
From this article, you’ll learn how to disable PHP warning or notice.
You need to edit the wp-config.php file.
Access the wp-config.php file
For accessing the wp-config.php file, you can use one of the below ways:
1. Enter your hosting control panel.
2. Through the FTP file manager.
3. Install and activate the File manager plugin
Steps to Disable PHP Warning or notice
1. Navigate to the WordPress root folder.
2. Find the wp-config.php file.
3. Click on Edit, or download it to your personal computer.
4. Inside your wp-config.php file, look for the following code:
define(‘WP_DEBUG’, true);
Or the following code:
define(‘WP_DEBUG’, false);
