I decided to move the captcha to an invisible captcha instead of attempting to build my own. Hopefully, everything is still working. We will find out if no one posts any secrets for a day or so. I'd say send me a message if you find something not working, but I moved the contact form to the same logic. haha
If everything is working as expected then it should be much easier to submit secrets, comments and all other forms on the site. Fingers crossed.
