Clone Test DB

It's a five star plugin just because it works as advertised, and it's easy to use it even though it has it's limitations, and you have to take a couple if (easy) steps.

1. Before cloning the database, edit the target folder's wp-config.php file, and change the database name to the target one (new installation's database). This is the code define( 'DB_NAME', "YOUR_DATABASE_NSME_HERE" );

2. After you clone the database, and if the cloned site is displaying a 404 (page not found) on the posts, pages, cpt, then log in to the backsite, and flash (update) the permalinks, this will solve the 404 errors.

Ok now the limitation: There is only one, and it is the fact that both websites HAVE to be on the same server, you cannot have a localhost -> live situation or vice versa for example, I hope the ability to log in into external databases will be added soon.



It's getting the job done.

Duplicate the table in another database and optimize it as a test site.
