Prevent Customers from Changing WordPress Address (URL)

A user changed their WordPress Address (URL) under Settings > General and their site stopped working. Oops.

Thanks to the wp-config.php file’s flexibility we can prevent users from accidentally doing this again.

Just open up the wp-config.php file and add the following two lines (modifying with the correct URL, of course):

define('WP_SITEURL', 'http://www.bobpotter.ws');
define('WP_HOME', 'http://www.bobpotter.ws');

Once updated, the WordPress Address (URL) fields is not editable from within the control panel:

Note: Do not put a slash “/” at the end
