I'm using this plugin to allow user login and register: http://bit.ly/1YY6lbX
My site users can no longer register to some of my sites because they are facing a issue with CAPTCHA verification. I tested this as well once all the details are correctly entered CAPTCHA verification always return as wrong CAPTCHA. It always says "CAPTCHA is not valid, please try again"
Can you please diagnose what's going on with those 2 sites? Support access is granted.
Its wired that Captcha works on some sites but not on others.
