In my site, The security image not showing on Contact user. You can see in the screenshot below.
But the image was shown when I login as Administrator User.
When I logged in as Non-Administrator user, the security image is not showing.
After checking with Firebug, there's a "Failed to Load resource" in http://fractionalpartners2.linux.stagingreview.com/wp-admin/admin-ajax.php?action=cf-captcha
Please help me to fix this issue.
