Having problem with templates not working

I am having problems with my Templates not working. Here is my Blog that i am making – https://www.renewalchattanooga.com/blog

Some of the main templates don’t work, like the sitemap. ALso when I created one it didn’t work. I even added the correct info at the top

<?php
/*
Template Name:referrals
*/
?>

but that page doesn’t work – https://www.renewalchattanooga.com/blog/referrals

Any help is greatly appreciated.
