Which file is keeping General Settings (WP URL)

The URL is stored in the database, not in a static file. Use these instructions to recover: Changing The Site URL ? WordPress Codex.

like it was suggested, that’s good to read. Specifically I think this will be the easiest way for you to fix this:

Edit wp-config.php

It should be possible to fix the site URL using a new feature –

Add these two lines to your wp-config.php, where “example.com” is the NEW location of your site.

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

That should be it. If it worked, stop reading this page now.

Great THANKS!
