PHP Page Trying To Open As Application/File?

I’m having an issue that my php-coder friend isn’t even sure the answer to so I’ve been told you guys are a big help. I’m about to use an old template to make a much broader site for my employers restaurant. This is the very simple layout that it’s going to be based off of, and the entire site works very well:

http://www.hurleyhafen.com/new/.

So I tried moving the website, as is, to a new server. I renamed what needed to be renamed in the header.php… This is where the [COLOR=darkgreen]new[/COLOR][COLOR=darkgreen] [/COLOR][COLOR=darkgreen]site[/COLOR] will be.

http://garibaldisrestaurant.com/new

Why would it try to open as an application? It’s the exact same .php file with a couple of non-major changes. I looked all through the code and there is nothing out of the ordinary to my amateur eyes.

Here’s the [COLOR=darkgreen]header[/COLOR] with the correct full-path changed: http://garibaldisrestaurant.com/new/header.php

Trying to think of what else might be affecting it.
I think it probably will be a [COLOR=darkgreen]server[/COLOR] issue with our host right? If you tell me to do SSH/linux stuff, go slow cause I rarely run shell commands like that

Thanks to anyone who knows, Im sure its a minor issue!
