  • Thank you.

    Thank you.

    With CloudFlare adding H Captcha, it completely broke my code and I couldn't find a solution until I found a github page with 10 stars.

    This is some great code on your part. Thank you for making this free publicly available code, it is highly appreciated!!! <3
