Cannot access Administration area

Hello ,

Last time, I cannot login to the administration area with the current username & password.
It's return the error message "500 - An error has occurred."

please help

Thank you.

That happened suddenly or first time you installed hot_start. Send link or ftp or something using "Report To Moderator"

I can login many time to customizing my site and I already send my site informations to "Report to moderator"

My site : www.thong-autoservice.com/2012/administrator

Thank you.

You installed some malicious component. You will need to log to ftp and to rename folder that component so you could prevent its loading.

Also you can edit configuration.php

set:

public $error_reporting = '6143';

so you could see error that may give you insight of witch component makes problem

after edit configuration.php ,the error still show the same message.
do you have any idea?

Thank you for your quick support.

Did you try to rename folder of new components you installed?
