August Infotech on "[Plugin: Multi-language Responsive Contact Form] captcha problem"

Hello ChDUP,

http://stackoverflow.com/questions/15000063/php-imagettftext-not-working-and-gd-installed

Go to responsive-contact-form/include/captcha_code_file.php

Try $font variable on 8th line as below:
$font = "./monofont.ttf";

And also FreeType library is required. If not, you will need to install Free Type library.

Thanks & Regards,
August Infotech
