I have installed the Mingle forum and the Captcha plugin on the following site: http://184.108.40.206/gardenmap (site is under construction)
I have left the registration required unchecked but have put a checkmark in the "Use Captcha for unregistered users. (I'm not sure what Requires GD library means and it is a broken link).
Under the Captcha options I checked all of the boxes for enabling Captcha.
When I access the site on Firefox (not logged in) - nothing shows up.
When I access the site on IE (not logged in) - I get a red x.
Obviously it isn't finding Captcha somewhere.
What do I need to do to fix this?
