This works great including on the latest version of Wordpress as of this writing. I'm using it with Contact Form 7.
In my opinion the person who says it isn't working is either logged in (and has the option to hide the captcha for logged in users), or didn't select "Contact Form 7" to enable it on contact form 7 in the settings (it isn't selected by default).
I am happy with this plugin. It's obviously not high security, but will prevent 99% of automated bots/spam in contact forms. I made the effort of rating it and writing this comment because it doesn't deserve 3.7 stars only. Thank you!
