Error in removing Portal Tool Area from Theme

Hi

In my Portal theme i had a Portal Tool Area with Search options.

My requirment is to removie it from the theme as we don't need it

Go to Content Administration

Portal Content--> Content Provided by SAP->End User Content-> Standar Portal Users

You can see Default frame work page.Open the same and untick the Visible Check box beside tool area iView in the frame work page.

Save the changes and refresh the page..

I made the setting,The tool area is not visible in priview...

But when i logged in as test user it is still there

How can i proceed

Thanks
