First of all the guide at webnots.com/how-to-move-live-wordpress-site-to-lo… is really a long one and as developers we want to make things happen ASAP.
So here's a better path ==> login to your WordPress Dashboard, > goto plugins and install the duplicator plugin wordpress.org/plugins/duplicator/, after that, locate the duplicator menu and create a package, follow the on-screen instructions to successfully build a package.
In the End, you'll have your entire WordPress site in just two files which is the INSTALLER & ARCHIVE. Download these files and copy them to you local development folder.
Note: you need to create a new database on your localhost before running the installer script.
To deploy the just downloaded files, simply goto localhost/folder/installer.php and follow the onscreen instructions to complete the setup.
