Access control list must contain at least one manager

What happened

You clicked File > Application > Access Control 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.
