So I reinstalled a fresh version of Zen 1.3.9F and attempted to reinstall a fresh version of this CAPTCHA mod "CAPTCHA using TTF & GD" which works fine on the old installation of Zen.

I get blank pages on all the related form pages where CAPTCHA is set to 'true' in admin config. I double and triple checked that all the proper mod pages were updated. The DB has the right info.

I notice this mod has no update since 2008. and is listed for 1.3.8 Zen.

Has anyone got it to work on 1.3.9? Is there a thread that has a solution or does anyone know of any?

Last, is there a better CAPTCHA or anti-spam solution for Zen-cart ?

thanks!!
