I have updated last week my forum from 1.2.10 to 1.3.5 and added extensions. I am particularly keen to stop 12-16 new registrations from spammers every day plus their posts so I added Antispam System. I have now installed, uninstalled and installed again. Each attempt to register myself under another user name and using a rarely used e-mail shows a broken icon where the CAPTCHA GIF should be. Why?
At least the absence of the GIF might stop all new registrations, but I do want real users to get through still.
I have the same problem, there is no captcha showing.
