Notifications you’re seeing in WordPress are not errors, so there’s nothing to be concerned about. These messages/warnings are usually intended for developers to assist with debugging and do not impact the functionality of your website..

If you’d prefer not to see these messages, you can easily disable them by turning off debugging in WordPress. You can either contact your hosting provider for assistance or do it yourself by following these steps:

  1. Connect to your website via FTP or using the file manager in your hosting control panel.
  2. Find and open the wp-config.php file.
  3. Look for the following line:
    define(‘WP_DEBUG’, true);
    and replace with:
    error_reporting(0);
    @ini_set(‘display_errors’, 0);
    define(‘WP_DEBUG’, false);
    define(‘WP_DEBUG_LOG’, false);
    define(‘WP_DEBUG_DISPLAY’, false);
  4. Save the file.

After doing this, the warnings should no longer appear.
