Wel, i just installed vbulletin, and when a user tries to register the captcha background shows up but the letters dont, does anyone know what may be causing this?
It being nulled doesn't really effect the way the CAPTCHA works. Have you got Javascript enabled, what browser are you using, what version of vBulletin are you using?
ya i kinda noticed some different image types for using with the captcha, im not really sure what to do with them lol. For the time being, i just set up some security questions
