Hello,
It's often hard to find the reason for 500 Internal Server errors, but here's a couple of things you can check and/or test.
Note: it has been reported that on GoDaddy,changes to .htaccess files need 10-30 minutes to take effect.
Cache problem
It's possible that it has to do with a cache problem, or a caching system not supported by GoDaddy. Check the following lines in your configuration.php file, and change them to the following:

public $cache_handler = 'file';
public $caching = '0';
public $session_handler = 'database';

Cookie Domain
In your configuration.php file, check if the following variables has any values. If they do, change them to this:

public $cookie_domain = '';
public $cookie_path = '';

$live_site variable
Verify your $live_site variable in configuration.php. It should be empty, or read

public $live_site = "www.example.com/home";

i check everything and still same error

Apache mod_rewrite is not enabled in the default XAMPP installation.
You must enable it.
