how to fix the url on my website?

my website , https://www.myozshop.com
I used a sub domain on my website temporally , com.myozshop.com.
but all the urls on the page are com.myozshop.com, how do I change it?
I can't find 'com.myozshop.com' in the files and datebase.

There are 2 files to change.

admin/includes/configure.php
and
/includes/configure.php

Change com.myozshop.com to https://www.myozshop.com

Thank you for your response so quick.
I did admin/includes/configure.php before and the backend is good.
I forgot uploaded includes/configure.php, I changed it just now.
but nothing happened. is it need some time?
How can I clear cache in the DB?

You must first make the file on your website read/writeable before uploading the new version.

By default it is read ONLY and will not allow the upload to overwrite it.
