A question for the pros, to help guide my way....

srpurdy is right, you're using curly apostrophes around your view string, probably because of copying and pasting from somewhere.

Code:

$this->load->view(‘signup_form’);

Change them to regular apostrophes and that should fix your issue:

Code:

$this->load->view('signup_form');
