Access control list must contain at least one manager
What happened
You clicked and edited the ACL, but you cannot close the dialog box because no manager is specified in the list for the server-based application. This might have happened because you deleted all entries in the ACL.
What you can do
Specify at least one manager for the application.
Note: In a local application, you can delete
the last manager, who might be yourself. If you intend to copy this application
to a server and keep access to it, make sure your name is in the ACL.
