1- Sorry to hear about the inconvenience. Kindly, please share your Site WP-ADMIN Login details in the Private Content field so that we can check these concerns on your Site and help you out accordingly.

2- Sorry to say but this Robotic Captcha doesn’t come from the Theme end. You might be using any third party Plugin for Captcha on your Site through which it might be showing on your Site. So, you need to check that for this.

Best Regards
