i tried the link

everything works fine on the front end.

when i go to the admin backend,if i choose preferences in the system module and try to save changes i get a 403 error:


Forbidden
You don't have permission to access /md/system/admin.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

any idea what the problem could be?
thanks for all your help!
