Hi Craig...wondering if you could give me some direction on phpcaptcha. I get the image in my form but the form submits successfully even with the image field empty. Any ideas on what I am doing wrong? Have read the quickstart guide repeatedly and it isn't giving me a clue. I am using it with UE4 and am wondering when you use it where you place the code that actually checks the user input for the captcha? I have tried it just above the closing form tag, above the submit button, and at the tail-end of UE4's code in the head but all give me the same results...form submits even if captcha is empty or incorrect.
