Editing/Deleting Locations

[shadows]

When trying to delete or edit a Country through our etano admin panel, we click on 'Save' or 'Delete' and get taken to a blank screen with the following address:
When editing countries:  ..../site address/admin/processors/loc_countries_addedit.php
When deleting countries: ..../site address/admin/processors/loc_countries_delete.php?country_id=1&o=0&r=10

We get similar results when trying to edit or delete a State or City.

The edit or deletion are not being accepted, so we are unable to add/delete/edit any locations

Any thoughts on what might be causing this?

It works on the demo site so it's probably something on your site. Could you please send me the whole error page you get?
