Form_validation class fails to locate rule-sets for certain URIs

[eluser]Unknown[/eluser]
I realized same problem when I try to have Form_validation class find validation rules set in config file.
It doesn't recognize validation rules set which is named correctly('controller'/'function') because of 3rd segment in the URI.

I modified CI_Form_validation class(line: 296) in my server with same way as Sholdinger.
My application uses bunch of form validation rules too. I'll keep testing the this fix.

Thanks Sholdinger,
BTW, I like your signature. keep doing try and error until success!
