Has anyone had this error before?
If so what is the problem?

have you loaded the form helper using $this->load->helper('form'); ?

If you will be utilizing the Form Helper alot throughout your site, I suggest using the config/autoload.php to load it. This will skip the step of adding it everywhere there will be a form.

After I did it works.
Thank you!
