if you try to browse to the captcha image directly:
it show the following error:
Fatal error: Call to undefined function imagecreatetruecolor() in /var/www/vhosts/wgonlinebrochures.com/httpdocs/webassist/captcha/wavt_captchasecurityimages.php on line 89
the captcha image relies on the GD Library and the True Type library being enabled for the php server, the error message means that one or both of these libraries are not enabled. You will need to contact the host to have these libraries enabled fro the php server.
In the server behaviors panel, (Window -> Serve Behaviors) Double click the universal Email server behavior and set the go to page to set a redirect.
multiple file uploads on the same page is fine.
