WP-admin/edit.php login probel

I all, thanks i advacne for any help.

I have managed to break my access to the wp-admin url. Somehow i must have changed it without knowing in the dashboard and now when I browse to the url it is trying an address which is wrong.

it is trying http://www.domain.comq/wp-admin/edit.php

Not the q after .com

can this be rescued please

thanks again
