i just realized that the "Really Simple CAPTCHA Version 1.2" i'm running with "Contact Form 7 Version 2.4.3" is not showing the captchas the right way. it worked when i set it up a while ago.
gd library is installed too:
i have no idea whats wrong there. the images are in the wpcf7_captcha directory together with the .php files.
thanks in advance
