iView not found: com.sap.portal.support.browse.default.

When I try to navigate to System Administration -> Support -> Portal Runtime -> Browse deployment, I get the following error:

Portal Runtime Error

An exception occurred while processing a request for :

iView : N/A

Component Name : N/A

iView not found: com.sap.portal.support.browse.default.

Exception id: 04:45_02/10/08_0037_13390350

I referred this thread [https://www.sdn.sap.com/irj/sdn/thread?threadID=188079|https://www.sdn.sap.com/irj/sdn/thread?threadID=188079] and removed the .bak extension from the file com.sap.portal.support.browse.par.bak and uploaded it in System Administration --> Support --> Support Desk --> Portal Runtime --> Administration Console ,in the Archive uploader.

But the problem persists. Could anybody shed some light on this issue?

Saurabh.
