The current version of codeigniter does not support
loading rules from config file and set_rules method .
Simply i commet the flowwing line Form_validation.php line 292

and its work fine .
The whole point of having the ability to include the rules from a file is to not use set_rules() in your code, so that behavior makes perfect sense.
