Okay, it's all working great. Thanks!

Sometimes though, the captcha can be hard for users to read. Is there a way for the user to refresh it? I'm using the aiContactSafe native captcha.

That's what the button "Not readable? Change text." does.

Well, sure. Except I don't see any button like that on my page. Nor do I see a way to make that button appear.
Here's my page:http://chemtrailsproject.com/index.php?option=com_aicontactsafe&view=message&layout=message&pf=1&Itemid=68

That is because somehow your template is hiding it.
If you look into the page's source you will see the button is there.
You can also see it if you load the form like this:
chemtrailsproject.com/index.php?option=c...id=68&tmpl=component

Notice "&tmpl=component" at the end.

So you need to debug your template to see why is it doing that.

Okay, thanks. That gives me the right place to look.
