 * Hi theo,
 * Glad to help. First of all, those are not “errors”, they are notices. They are
   nothing to worry about. They should never, however, be displayed on the front-
   end of any live, production site. Displaying PHP/debug infos can be a security
   risk. You can search online and/or ask your host how to disable them so they 
   are not displayed.
 * That said, for the PHP notices you are seeing, it could be because of misconfiguration..
   can you let me know what you have for the following settings:
 * – Challenge Question
    – Challenge Response – Display Captcha

 * Hi Jeff
 * Thanks a lot for your instructive response. I wasn’t aware of the security risk
   of turning debug on. Well, it’s off now.
 * The plugin configuration that caused the notes was:
    challenge quesion: 1+1= 
   challenge response:2 display captcha: off
 * Since you narrow the problem to these there fields, i tested the behaviour with
   display captcha: on.
    With this setting the notes are gone.
 * The reason why i turned display captcha off, was, that the plugin already provides
   an empty field (something like a honeypot, right?) and i’ve read in many articles,
   that captcha is an obsolete technique and considered user-unfriendly.
 * But, anyway, the plugin works well.
    Thanks a lot for providing Contact Coldform.
   Great contribution.
 * regards
    theo

 * Ah, thanks for the feedback, I’ll make sure the notices are resolved for the 
   next update. Technically the captcha is not a honeypot, more like the opposite
   of a honeypot, but it is totally fine if you do not want to display for whatever
   reason. It’s all good man, thank you very much for the feedback – I appreciate
   it. Kind regards, Jeff
