Works well… with a little bit of help sometimes

This is a wonderfully simple plugin.

It took a while to get it working, but that is not because of this plugin, but because Contact Form 7’s Form Tag Generator did not work in editing the form. Instead of adding [cf7sr-simple-recaptcha] , it repeatedly gave an error messsage saying: “To use reCAPTCHA, first you need to install an API key pair. For more details, see reCAPTCHA.”.

Which I had already done of course. Simply hand-copying the [cf7sr-simple-recaptcha] in to the bottom of the form worked fine though. This error is just one to ignore.

If this was sorted out with the Contact Form 7 makers, I would happily give the 5 stars.


When one attempts to generate the Site key and Secret key, the link just returns an error.

“The 502. That’s an error.
The server encountered a temporary error and could not complete your request.
Please try again in 30 seconds. That’s all we know.”

At least the captcha I was using (really simple captcha) stopped some spam. This program does nothing – except display its shortcode on the contact form!

Great Plugin – Costel is very patient

Purchased the plugin and didn’t know how to install. Costel worked with me very patiently and through many computer problems to get it working. Not sure how many spam messages it will handle since it was just installed but it appears to work great so far.

It works on mobile and desktop

This is probably one of the simplest captchas for CF7. It was very simple to implement and grabbing the appropriate key from Google is necessary.

It works seamlessly in both desktop and mobile environments.

If there are issues, there may be other plugins interfering or you don’t have the latest version of the required software.
