when i try to view the image directly:
wavt_captchasecurityimages.php
i get an error saying:
The image “wavt_captchasecurityimages.php” cannot be displayed, because it contains errors.
We will need to know what those errors are to find a solution
try adding the following code to the webassist/captcha/wavt_captchasecurityimages.php file at line 1:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
