Currently, the plugin is only working for members of our site. Whenever a guest tries to leave a comment and enter the captcha code the following error message appears: "Invalid Data: Please go back and try again." I have tried disabling captcha and the problem still occurs.
Here is s page that the plugin is being used on: http://familyguiding.com/create-outcomes-psch/alexis-nivens-lmsw/
Hi Jayna56,
This is not wpDiscuz issue. Some plugin or the theme tries to send additional information on comment submit. it may be AntiSpam or other CAPTCHA plugins. Please deactivate plugins one by one and find the one which causes this conflict. Then let us know which one was that. Also to get correct test result you should delete all cache after each plugin deactivation and reload guest page with CTRL+F5.
Awesome! It worked. We had a plugin called "WP Captcha Free" installed. Once deactivated everything works fine.
