Inadvertently changed WP URL & Site URL in Gen Settings

The WordPress URL for my site is supposed to be . In the General Settings screen, I inadvertently changed both the WordPress URL and the Site URL to the http://flashbackfab.com/new. I now get a page error and only a list of the menu items. This site is hosted on Go Daddy, and the “new” site is a subfolder under the root domain, but it has not been launched yet. I have looked in the index.php and wp_config.php and cannot find where to correct the URL so I can continue working on the site.

Can anyone help me find where to correct the URL to in the FTP File Manager?

Thanks! Joni
