移动Joomla后的错误！ 从localhost到live server的网站

I've got a Joomla! 2.5 website on my localhost and it's working fine. I need to move it to a live server so I've followed some tutorials on the Internet to make sure everything's fine so I did it like that:

1. export database from localhost to .sql file
2. install clean Joomla! 2.5 on server
3. move all the files and folder from localhost to server (except configuration.php)
4. deleted all tables from server's database and imported database from localhost

After these steps site doesn't load at all giving this error:

Fatal error: Call to a member function get() on a non-object in /home/users/zsrkm/public_html/templates/beez_20/error.php on line 10

When you enter http://www.zsrkm.pl/administrator there are even more errors. I'm very grateful for any help. Thanks in advance.

The easiest way to move a Joomla website is Akeeba Backup and Akeeba Kickstart.

Akeeba Backup backs up the database and the files into one file which makes it easier to move. Once you have created the database on the target server, upload kickstart.php and the backup file and then run kickstart.php to recreate the website.
