website online problem

[eluser]Gerep[/eluser]
Hi guys,

I'm new with CodeIgniter and I just send my files online on the following link: http://anuncio.redenoos.com.br/ but it seems to have an error.

I've created a login. To generate the error just click on "Entrar", should display messages on the required fields but I got this error.

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

My steps:

Folder: system/application/config
- config.php -> $config['base_url'] = "http://anuncio.redenoos.com.br/";
- database.php -> database configuration;

Thanks in advance.
