Few months ago, I developed two template pages on wordpress 3.1 and they were working fine. Now, I installed latest wordpress software. I created a new page with the same name and selected the template. But the link is showing a "404 Not Found" error.

My site URL goes like this: <http://localhost/myBlog/about>

where "about page" has to use a template. The same permalink is shown when creating the page but viewing page is showing 404 error. It's weird. May be some permalink issue?
