Applying a captcha to contact forms successfully

Hi!

If anyone was having issues with their Really Simple Captcha plugin after the most recent WordPress update and figured out a resolution, please share with us… Our website Visitors cannot subscribe to our mailing lists because the Really Simple captcha wasn’t working. The image doesn’t populate. I reinstalled the captcha but it still wasn’t working so I removed it from our forms. I then installed another captcha plugin which may work but I am unfamiliar with the coding text we need to apply to our forms so that the captcha comes up. The new plugin I installed is: reCAPTCHA

Any advice or direction is greatly appreciated!
