Hi all,
we also face this issue with DS 1.5 SP1 and launching DS Reports on a BO BI Platform 4.1 from Enterprise Portal 7.4.
We use Chrome with version 47.0.2526.80.
Unfortunately, I cannot reproduce this error on my machine but other users complain about this popup.
Maybe this has something to do with the settings in Chrome?
Regards,
Philipp Hinnah
