How to disable security and make free accessible form

Hello,
I want to create free accessible form for general public form.

I tried to use:
sc_apl_status(“E-prijava”, “off”);
but unsuccessful.

I also turned off:

  • Use Security
  • Use Password
  • Enable direct call by URL
  • Enable CSRF

I am using Chapta that I prevent robot entries.

Please advise what to do to make it usable without of using password.

Thank you!
