can't save form

I can't edit the form and save it. I receive a "Forbidden You don't have permission to access /administrator/index.php on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. chronoforms 6" error message. Any ideas how to fix? i am logged in as admin.

Hi sifaka,
​
I think that will be a server setting of some kind. Can you log in as a SuperAdmin to see what is happening?
