Prima, funktioniert auch auf meiner WP 6.9 einwandfrei
Super simple! Einfach in Contact Form 7 Version 6.1.4 einzubinden. Danke. Meine WordPress Installation: Version 6.9.PHP Version 8.4.15
Bad
I’m sorry to have to give this a bad rating. The amount of spam with Contact Form 7 was enormous. I had to remove it.
Works great with Gravity Forms in 2024!
Nothing but positives. We added this to our Gravity Form in order to obtain the dynamic math captcha. One can create a simple math captcha in GF but not dynamically changing for each form load insof

Want to love it

PHP Notice: Function _load_textdomain_just_in_time was called incorrect
PHP Notice: Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. Translation loading for the <code>math-captcha</code> domain was triggered too early.// This warning fills
Excellent
Been using about 2 months. Works a treat.
