I need to disable/remove recaptcha from a development site, in order to be able to test form submissions.
Solution:
You can go to Toolset Settings page-> Forms, setup the reCAPTCHA API key temporarily, then remove the recaptcha field in the post form.
Or you can switch to "Expert mode", remove the recaptcha field shortcode directly:
[cred_field field='recaptcha' class='form-control' output='bootstrap']
