I've seen this topic in the forum but none of them had answers.
But I'm pretty sure I know the problem I have.
This functionality was working fine in my test site which was running on CentOS.
Then I put my joomla site in production which is running Ubuntu. Unfortunately the Ubuntu server has minimal installation which meant it was bare bones and needed packages/libraries have to be installed (apt-get install....)
So the problem I have here is that I'm most likely missing a library at linux and/or php level. Can you tell me what libraries does the Captcha functionality rely on so I can install whatever the missing libraries are.
