Reload via button is no longer working.

[qlikconsultant]

We build a button that reloads an application on click.

Worked fine so far. But since a few days it is no longer working and we get this error in the access point:

If I start the app in QlikView Developer. It's works fine.

My guess is that the server administrator changed something on the server.

Has anybody an idea what could causes that?
