I created a page called Sitemap that contains a Page List block, a simple page. It can be found at /sitemap, or at least it used to be found there. Now if I try to navigate to the /sitemap page, it gives me the sitemap.xml contents. What's up with that?

I built the site on one server and then when we launched, the site was moved to another server. Both servers were built off of the the Digital Ocean LAMP image so there should be little difference.

Any ideas?
