Easy to install. I used to link and got a public and private reCAPTCHA key. I checked the box in settings to use reCAPTCHA. Saved. The boxes were available for me to paste the keys. I filled out some of the other boxes for personal messages. Saved. Created and published a page with the short code. However the reCAPTCHA nor any of the text entered in the settings displays.
EDIT: The problem I encountered was a conflict between this plugin and Jetpack. Once I disabled the Jetpack contact form, this plugin worked flawlessly. Thank you.
