Error when saving the settings with User Access Manager

When I go to save the settings on the message when users don’t have access it goes to a page not found. I have setup the groups and the plugin works just like I want but the redirect page or change in message for not access when I try to save sends to a page not found.

wp-admin/admin.php?page=uam_settings is the location after the domain url it is looking for.

Any help would be great.
