Hi,

When you first renamed the page a 301 redirect was created from the old url to the new url. Then when you changed it back it would not create another redirect because this would cause an infinite redirect loop.

Look for the redirect under Administration > Advanced Tools > 301 Redirect Manager and delete it.

Note however, that creating pages does not actually create .aspx files on disk, CMS pages are virtual and served from the database.

Hope it helps,

Joe
