OK, now when visiting the captcha page:
WAVT_CaptchaSecurityImages.php
it shows the following error:
Fatal error: Call to undefined function imagettfbbox() in /Library/WebServer/jeffcou/store/WA_ValidationToolkit/WAVT_CaptchaSecurityImages.php on line 129
this error means that either the GD or True Type libraries have not been enabled in the PHP server settings. you will need to contact the host to have them enable both the GD and true Type libraries.
