[Problem] Form helper in Codeigniter v3.0rc

Yes, I've tried to deactivate it and it was the same result :/

In fact we need to deactivate global_xss_filtering in the config file and load the security helper to applicate it in the form validation rules ?

I've tried it and apparently it works.

But, when I use the csrf protection (in config file) I have this error when I try to submit a form :

The action you have requested is not allowed.

PS : Sorry for my bad english :/
