2. Open the wp-config.php file with a text-editor and insert this line:
to the end of the file, just before the if ( !defined(‘ABSPATH’) ) line.
3. Don’t edit or change any other stuff in the wp-config.php file, unless you know what you are doing. Save the changes and upload this file back to your server. Make sure you overwrite the existing copy in the server.
