WordPress and Blog Addresses

I am new in WordPress and I have this problem that I like to solicit some help:

Here is the example site: https://www.sample.com/blog

on my server, the places that contains all the files are :

/home/sample/public_html/blog

In this case, what should I specify in the Setting/WordPress address (url) and blog address (url)

I am currently setting them to https://www.sample.com/blog. and things seems to work well. However, I ran into some problem with iNove theme. Here were the warning from the iNove theme:

Warning: main(templates/header.php): failed to open stream: No such file or directory in /home/sample/public_html/blog/wp-content/themes/inove/header.php on line 62

Warning: main(): Failed opening ‘templates/header.php’ for inclusion (include_path=”) in /home/sample/public_html/blog/wp-content/themes/inove/header.php on line 62

Please help. Thanks!
