MSS: Team --> General Inoformation page is getting displayed as blank

In Manager Self Service --> Team --> General Information

We are using some of the iview which are embedded in a page. IViews are,

Employee Search, Monitoring of tasks, Company Property, General Data, Personal Data, Absence Days, Message Box and Data Tracking.

This page and all the iview are working fine on other systems (Dev and production) but its not working on test system. The page is getting displayed as blank. No error message or no dump.

Has anyone encountered the same problem?

Thanks
