Upgrading Wordpress version

So if you happen to have an old Wordpress version and want to upgrade to the latest, and somehow automatic updating doesn't work, you can always update/upgrade manually. It's pretty easy.

1. Backup your existing website (files and db)
2. Download the latest Wordpress zip file, and extract on your local machine
3. Access your site via FTP and remove/delete/rename (whichever suits you) these 2 directories in your current installation wp-admin and wp-includes
4. Upload the new wp-admin and wp-includes from the newly extracted zip file
5. Then upload the rest of the files overwriting the existing ones
6. Check your admin site, WP might ask you to update your database.

That's it.
