I'm sorry but I'm not sure what's in your current setup right now because it's locally hosted. With that said, I could not recommend if you're going to continue following the resource or video you referred to as we have no means to check it nor compare it to your live site like what @Rad has said:
I believe @paul.r assumed you know how to completely clone a site especially taking into account the proper migration of Cornerstone data and do the comparison yourself when he suggested this:
Also, based on the details you provided, the issue was not caused by the theme. It is obviously caused by incorrect migration or WordPress setup. Please note that we do not have support for such issues. If you're having a hard time following the resource we suggested, I'd recommend that you hire a third party developer to do the cloning for you.
Please look for hosts like pantheon.io which offers free online development sites. Once you get the clone of your site up and running, give us WP admin and FTP access to it so we could check your setup and see what's causing the issue. Please remember, that this is outside the scope of our support like I've said as this is not just an issue with the theme. It's an issue with your WordPress setup.
If you can build your site in the new domain and from scratch again, that will be the least technical solution.
