tags not redirecting to home page

Hi,
i just installed this plugin. But what happens in my case is ” i have removed some of the tags from my posts which already been indexed in google. When i click on that google results page, it shows nothing found page instead of redirect to home page. ” so what to do to do so ?

Thanks in advance,
Chenna Reddy
