# [Plugin: BackUpWordPress] php error after upgrading to 1.6.2

 * After upgrading from 1.5.2 to 1.6.1 Backup failed due to missing file /usr/share/
   wordpress/wp-includes/js/tinymce/plugins/safari (which is a link to a non existing
   file or directory ‘safari -> ../../../../../tinymce/www/plugins/safari’) This
   file never existed by the way.
 * I decided to upgrade to 1.6.2. Now the backup is working againg, but still WP
   is showing an error:
    “BackUpWordPress detected an issue with your last backup.
   php: 8:Use of undefined constant SECURE_AUTH_KEY – assumed ‘SECURE_AUTH_KEY’:/
   usr/share/wordpress/wp-content/plugins/backupwordpress/functions/core.functions.
   php:335″
 * Any suggestion what is wrong and how to fix this?
    Thanks Adrie

 * This is a known issue that will be fixed in the next version.
 * You’re getting the error because your missing the following from your wp-config.
   php
 *     ```
       /**#@+
        * Authentication Unique Keys and Salts.
        *
        * Change these to different unique phrases!
        * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}
        * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.
        *
        * @since 2.6.0
