Blank Admin login screen

[Stefware]

Hi

 

After an unsuccesful upgrade and backroll, iv ended up with a blank admin login page and the following error

 

Notice: Undefined index: adminnotfound in /var/www/monteringsudstyr.dk/public_html/classes/Dispatcher.php on line 341

Fatal error: Class name must be a valid object or a string in /var/www/monteringsudstyr.dk/public_html/classes/controller/Controller.php on line

 

If i count correct line 135 is the bold line:

 

    public static function getController($class_name, $auth = false, $ssl = false)
    {
        return new $class_name($auth, $ssl);
    }

 

Anyone have an idea whats going wrong
