We have upgraded the 5.5 system to 7.1. We have the functionality of coming back to the user portal and open the default wide pane after submitting a request.In 5.5 it is working fine.But in 7 after submitting the request it is showing me a blank screen at the right side.We are still using the classic portals of 5.5 in upgraded 7.

Any help or suggestion is highly appreciated
