It seems like the password must be typed and not copy/paste at least on the install part. good to know ;o)
The default login is : admin The default password is : 123123
If you are having troubles and want to reset it to a different password, just run at your sql database:
[sql] SELECT * FROM admin_user; [/sql]
Then, find the username you want to modify in the listing provided – ‘admin’ in this example. Then, to update the password, type:
[sql] UPDATE admin_user SET password=CONCAT(MD5(‘qXpassword’), ‘:qX’) WHERE username=’admin’; [/sql]
‘qX’ would be changed to whatever you want it to be and same goes for ‘password’
You can also do this in phpMyAdmin, find the admin_user field and choose MD5 when updating password.
If you want to add a new admin user, you must not only create a new entry in the table ‘admin_user’, but you also have to insert an entry in the table ‘admin_role’ which has to be associated with the user by the field ‘user_id’.
