Blank content area

Hi all

I have created a custom framework page by copying the Actual default Framework page.I arranged all my iviews inside the customized framework page as desired and it was working fine.When i try to add more than one iview to the content area in the page the ivviews are always added to the navigation panel.So i removed the iviews from the page and after removing the iviews am not able to see any content in the Content Area(not even the defualt content for tabs like Content Administration, User Administartion,etc).Am not able to view any content.

Pl help me in solving this problem immediately.

thanks in advance
