rsnapshot plugin shows empty popup window when button "Run" is pressed

Hi there,
when I select a rsnapshot job and press "Run" the popup window "Execute Backup Job" shows first "Please Wait" and stays then blank. In the rsnapshot log there is a corresponding log entry which shows the executed job without error.
Does someone has a hint how to bring back the content (rsnapshot status messages) in the blank window?
Thanks in advance,
topi

Sorry, I missed to disable the option "Error Output Only" in the rsnapshot job definition. Disabling this option brought back to content to popup window.
So, no issue, just my mistake.
