reconfigure to Manage whole website?!

If you have root access, you can change the document root in the virtual host in your Apache configuration file.

<VirtualHost *:80>
DocumentRoot /www/example2
ServerName https://www.example.org

# Other directives here

</VirtualHost>

If you have any other website with index.php file in root then I am afraid to say that you will have use wordpress from directory as you can not have two index files in folder.

Do you have a running site? URL?

Thanks for replaying,

chomachomachoma Could you elaborate more please, because I don’t quite get it !

govpatel Indeed, but I don’t want to uninstall the current WP because that will mess up the theme for the blog on the website.
The only reason I am trying to do this is because I wanna apply a whole new theme for the whole website using WP, unless there is another approach then I appreciate the guidance.
Thanks

Yes.
This is the running website https://www.walayah.org/

However, I can’t simply overwrite/replace the index.php & .htaccess files in the root because they will miss up many other essential things.

Do you have different copies of the files in your /blog and root?

Yes. I do.

Your site is working fine now. Check it.

I have never said that the website is not working, so I wonder what you are referring to!
