How to change the WordPress URL using the wp-config.php file
To change WordPress URL you need to put this code into the wp-config.php file:

- The domain name should not have a / at the end of it
- Hackers love the wp-config.php file. After you edit it, change its files permissions to 444 to make it hard to tinker with.
- While you have the wp-config.php file open, make sure the SALTS are good. More on that
