Interspire Product Knowledge Base

This is commonly a configuration problem on your server. The quickest fix is to disable Interspire Website Publisher from using the PHP GD Library (It doesn't matter if you don't know what this is)

Edit the file:
/includes/classes/class.captcha.php file

Inside that file you will see a function called AL_CAPTCHA(). Simple replace this code:

if (GDEnabledPNG()) {
    $this->type = 'dynamic';
}else{
    $this->type = 'static';
}

with:

$this->type = 'static';

That should fix the problem. If it doesn't please post a support ticket with your details and we'll do what we can to fix the problem.
