The Captcha plugin adds a captcha form into web pages. This captcha can be used for login, registration, password recovery, comments forms. It protects your website from spammers by means of math logic, easily understandable by human beings. All you need is to do one of the three basic maths actions - add, subtract and multiply. You will not have to spend your precious time on annoying attempts to understand hard-to-read words, combinations of letters or surreal pictures. The plugin is compatible with BuddyPress (Registration form, Comments form, "Create a Group" form), Contact Form 7 and Subscriber.

  2. I have installed Captcha Pro and enabled it for comments. It appears on the comments form but when the commentor enters the response nothing happens. When the commentor hits submit, the comment is rejected because the Captcha answer is wrong. Any help will be appreciated.


    • Hi Pat,

      Unfortunately, your problem is not clear enough – is the captcha displayed on the comments page? If yes, the problem is unclear. Is the comment submitted or does the error occur if the captcha is entered correctly? It would be much clearer if you provided a link to the page with an example of the comments form.
