Change Blog URL But Internal Pages Still Redirect to Original URL

Hi Guys,

I changed my blog URL from xyz.com/ to xyz.com/blog…

The page loads fine on xyz.com/blog and when I mouseover the links all the links correctly point to xyz.com/blog but when I click on any of the links it takes me back to the old URL i.e. xyz.com

For example.. when I mouse over a URL I see..

xyz.com/blog/article.html but then I click on it, it takes me to xyz.com/article.html.

All the internal links have same behavior..

Plz help..
