Contact form captcha error php5.2
I have been using the contact form pack with php 4.3 for some time now with no problems.
I experimented with using php-cgi 5.2 and the captcha image did not generate (all other php scripts worked fine)
Now I have moved servers to one with php 5.2 with gd2 enabled and again the captcha image has stopped being generated.
If I access the captcha image directly, ie.
no image is generated, instead this error is generated.
Fatal error: Call to undefined function imagettfbbox() in /home/username/public_html/WA_ValidationToolkit/WAVT_CaptchaSecurityImages.php on line 125
Line 125 is -
$textbox = imagettfbbox($font_size, 0, $font, $captcha_string);
Help would be appreciated.
Contact Form Version is 102
