Problem with Live Validation

This looks very strange for me.

I have added Live validation to my project, but later I removed that
from project due to some reason. I roll back to old version too. Now if
I look at my file there is no code related to Live Validation. But after
rendering the rhtml if look at the view source there is code for live
validation. I dont know from where its loading. Even some time I wonder
whether i am working in correct project or not?

I checked in all the file in layout there is no link to Live

Can any one suggest what could be the problem???
