Sydney theme is giving an error

I just not installed this theme on my desktop and tried to take a look. i used wamp server to do all this. I found this error on typing localhost/sydney

( ! ) Fatal error: Call to undefined function get_header() in C:\wamp64\www\sydney\index.php on line 14
Call Stack

Please help


Can you please try to activate default Twenty Sixteen theme and see if it works?

Kind Regards, Roman.
