After migrating the dev version of my site to root directory of the host my custom login page is still trying to route to the dev environment (which has subsequently been deleted)

Meaning i get this error message:

Not Found

The requested URL /americanmedium1/index.php/login/do_login/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


Which files do i need to edit to fix this?

Thanks
