Even though they are supposed to, some themes do not handle comments on Pages. Make sure your theme does, before trying anything else. You can Live Preview a Twenty* theme to verify that your comment settings are correct. Also, there are choices on the Settings > Discussion page that will close comments according to time passing, so make sure that is not the case either.
