Migrating from localhost

Thanks
I did these steps
Download a copy of the main wordpress files from your OLD blog to your hard drive and edit wp-config.php to suit the new server.
Go back to your OLD blog and go to options and change the url (both of them) to that of your new site.
Again, download your database (but keep the old one just in case), upload this new database and the copy of the wordpress core files with the edited wp-config.php to your new server. Thats it!

Still , I got the same error

What more do I need to do?
