 * Hi,
 * When I set wp-config.php: define(‘WP_DEBUG’, true);
 * It causes the following error message:
 * <b>Notice</b>: has_cap was called with an argument that is **deprecated** since
   version 2.0.0! Usage of user levels is deprecated. Use capabilities instead. 
   in <b>C:\Bitnami\wordpress-4.9.8-3\apps\wordpress\htdocs\wp-includes\functions.
   php</b> on line <b>4088</b><br />
 * Any ideas on why?
 * Thanks,
    –Dave

 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and use one of the default (Twenty*) themes. If the problem goes away, enable
   them one by one to identify the source of your troubles.
 * If you can install plugins, install “Health Check”: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
   On the troubleshooting tab, you can click the button to disable all plugins and
   change the theme for you, while you’re still logged in, **without affecting normal
   visitors to your site**.
