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

Beware: Blocks login

Blocks login even if login protection is not checked in dashboard. Moreover, the right answer does not allow to login. You get locked out your own WP site.
