Exception: An error occurred when trying to create a controller of type 'PublishReportTasksController'. Make sure that the controller has a parameterless public constructor.
It is due to a path in the home page that is not accessible by users that are not logged in.
The error appears when a user that has not logged in attempts to access the Qlik NPrinting web console.
Log in to the Qlik NPrinting web console and the error should disappear. This error does not cause report creation failure.
