redirect – production site routes to staging site after cloning

Check your production site’s wp-config.php file for one or both of these lines:

define( 'WP_HOME', 'https://example.com' );
define( 'WP_SITEURL', 'https://example.com' );

…and set them as appropriate if they exist.

These constants will override the settings in the database if they’re present. See Editing wp-config.php for details.
