Invalid Verification Code Entered - Events Booking

I've already done that.
Maybe you have misunderstood - please refer to the updated ticket from last November.
I installed JD CAPTCHA, set it to the default in Global Configuration, and tried a group registration.
JD CAPTCHA shows TWO dialog boxes - like it did with the site I installed it on last November - and I gave you access to the site and you made a change (?) to fix it.
I checked the URL for the JD CAPTCHA download and it shows that it has not been updated.
 

There was a small issue with the captcha plugin. I believe I updated the fix to server, but I just uploaded it again

If anyone is having the issue, please download the plugin, and update it to your site to have the issue sorted

Regards,

Tuan
