We have upgraded the portal from 7.0 to 7.4, After upgrade web dynpro z iviews are displaying blank page in IE9, 10, 11. Web dynpro java standard iviews are working fine.
It is working fine when we change the browser compatibility settings, But users have different type of browsers and OS.
Please suggest whether any solution is there to change the settings in Portal it self.
Your response will be appreciated.
