error_messages_visibility_in_drupal_10.md

To configure the error messages visibility, set an appropriate configuration in the settings.php file

// Show all error messages, including notices and coding standards warnings.
$config['system.logging']['error_level'] = 'verbose';

File: /path/to/docroot/sites/<SITE_NAME>/settings.php.

Then clear the Drupal cache.

Here are the possible values you can use for error_level:

• hide: Do not display any errors.
• some: Only show errors and warnings.
• all: Show all errors (notices, warnings, and errors).
• verbose: Show all errors including notices and coding standards warnings.
