How do I remove recaptcha?

Hello, as the title says, how in the world do i remove the recaptcha(later recap)? It’s not like i have errors with it, but I am making my custom register page and unable to add the submit button to work properly without the recap. So my question is how do i remove the recaptcha from register form, now i removed the code of recap, but still not able to register new users, anda yeah so i hope you will help me! Thanks in advance. Here is my custom register   http://ausmex-airline.epizy.com/registration/ (custom login works perfectly: http://ausmex-airline.epizy.com/login/ ) And aswell i have the error: http://ausmex-airline.epizy.com/VA/index.php/registration(see at the top)
