When I tried to migrate one of ZEN applications to IRIS from 2018.1 I'm faced with the issue with Login Page, in this case used some ZEN page, completely customized. But when a user tries to get access, he gets the error like below.
The requested URL /csp/user/User.Login.cls was not found on this server.
I tried to test it with a fresh just created login page class
Class User.Login Extends %CSP.Page
ClassMethod OnPage() As %Status
Set it to /csp/user application as Login page, and
