Setting $cookieSecure = true;

When I set $cookieSecure = true; in Config/App.php and submit a form I get the following error:

BASEPATH/Security/Security.php at line 193

PHP Code:

186         }
187 
188         // Do the tokens exist in both the _POST and _COOKIE arrays?
189         if ( ! isset($_POST[$this->CSRFTokenName], $_COOKIE[$this->CSRFCookieName])
190              || $_POST[$this->CSRFTokenName] !== $_COOKIE[$this->CSRFCookieName]
191         ) // Do the tokens match?
192         {
193             throw new \LogicException('The action you requested is not allowed', 403);
194         }
195 
196         // We kill this since we're done and we don't want to pollute the _POST array
197         unset($_POST[$this->CSRFTokenName]);
198 
199         // Regenerate on every submission?
200         if ($this->CSRFRegenerate) 


My form uses the csrf function to create a token. Why is that a problem?

Simpler is always better
