Title: "Please go back and complete the CAPTCHA" appearing when registering multiple participants for an Event
ThreadText: # "Please go back and complete the CAPTCHA" appearing when registering multiple participants for an Event
  
  (Asked by: username_0 on 2017-11-10)
  
  We're on CiviCRM 4.7.25 and Drupal. We have the CAPTCHA and ReCAPTCHA modules enabled, and ReCAPTCHA is enabled on a profile we use for event registration.
  
  We're seeing a new error (which never used to happen!) when registering multiple participants.
  
  Behaviour is:
  
  * User is not logged in to Drupal
  * User enters details for Participant 1, and completes Captcha
  * User enters details for Participant 2. No captcha appears (good!). User tries to proceed to next step and encounters alert "Please go back and complete the CAPTCHA at the bottom of this form"
  * User can't progress any further with event registration
  
  The only problem being, there is no captcha!
  
  For now, we have disabled Captcha on this profile, having drawn a blank on other fixes. Any suggestions gratefully received!

  Looks like a bug- see comments
  2 possible workrounds
  
  1) Limit to single participant registration
  
  2) Create new profile w/o captcha and use this as profile for additional participants
  
  Or as you suggest disable captcha for profile entirely
