Can't login to Joomla 1.7 admin

Question

UPDATE: I checked the prefix_users table in phpMyAdmin and the user I was trying to login with has the usertype field set to deprecated

I'm running a site on Joomla 1.7, and recently I noticed I can't login to the administrator panel. I'm getting this error:

Username and password do not match or you do not have an account yet.

I know the username & password are correct because I checked the configuration.php file. I set permissions to the configuration.php file to 0644, and I've tried setting

public $cookie_domain = 'mydomain.com';
public $cookie_path = '';

Initially it was public $cookie_domain = '' but that didn't change anything.

I tried both mydomain.com/administrator and www.mydomain.com/adminitrator

I also tried with a private browsing session in order to avoid any local cookies that might have been stored on my computer in the past.

Note: after a failed login I'm redirected from mydomain.com/administrator to mydomain.com/administrator/index.php

Answer 1

SOLVED: changed usertype from deprecated to Super Administrator and then I used this MD5 hash generator to update the password.

I think it was because the encryption was wrong...
