Captcha in About Us, not displaying

The Captcha security options is showing up and causing an error in the about us section of power store, would love to fix it or just kill it, checking our phpinfo.php shows GD support enabled but still no graphic and hence no way for the customer to continue.
the site is : www.bbmdrum.com
running on an apple xserve server under snow leopard 10.6

Any thoughts would be great.
Thank you

In addition to the GD Library, the True type library must also be enabled.

trying to access the file that generates the captcha image:
WAVT_CaptchaSecurityImages.php


shows a blank screen.

this means that there is a php error occurring but error reporting is turned off.

add the following code to line 1 of the that page to turn error reporting on:

<?php

error_reporting(E_ALL);

ini_set('display_errors','on');

?>

The PHP line for error reporting has been turned on, the error listed on line 126, I have no understanding of this: $textbox = imagettfbbox($font_size, 0, $font, $captcha_string);

Thanks

the imagettfbbox() function requires both the GD library and the FreeType library.

function.imagettfbbox.php


in your phpinfo file, make sure the free type library is also enabled.
